[tex]\\ \sf\longmapsto Area=LB[/tex]

[tex]\\ \sf\longmapsto Area=(x+4)(x-9)[/tex]

[tex]\\ \sf\longmapsto Area=x(x-9)+4(x-9)[/tex]

[tex]\\ \sf\longmapsto Area=x^2-9x+4x-36[/tex]

[tex]\\ \sf\longmapsto Area=x^2-5x-36[/tex]

Step-by-step explanation:

Solution,

Given:-

Length=x+4

Width=x-9

Now,

By applying the formula for area of rectangle, we get

Area=length×width

Area=(x+4)(x-9)

Area=x(x-9)+4(x-9)

Area=x²-9x+4x-36

Area=x²-5x-36

Answer:

When a pair of parallel lines is cut with another line, known as an intersecting transversal, it creates pairs of angles with special properties.

Step-by-step explanation:

CORRESPONDING ANGLES are equal

<1 and <5 <2 and <6 <4 and <8 <3 and <7

ALTERNATE INTERIOR ANGLES are equal

<3 and <5 <2 and <8

ALTERNATE EXTERIOR ANGLES are equal

<1 and <7 <4 and <6

VERTICALLY OPPOSITE ANGLES are equal

<5 and <7 <6 and <8 <1 and <3 <2 and <4

COINTERIOR ANGLES are supplementary, meaning adding their measurements together will give you 180°

<2 and <5 <3 and <8

Answer:

-4 and -2.

Step-by-step explanation:

First of all,... OH MAN,... that is serious brain twisting logic (if you can call it logic) and to be fair I had to ask a math expert person I'm acquainted with,... cause I didn't know either,... so nothing to be ashamed about,...

If we let 2x equal the lesser of the two consecutive EVEN integers, and we let y equal 2x+2 be the greater of the two consecutive EVEN integers,

(For example, this is like x = 1, so 2x=2, y=4  or  x=7, so 2x=14 and y=16, we add 2 to the lesser even integer to get the next CONSECUTIVE even integer.)

This, y=2x+2,  is one of the equations we need.  To get the other,

 "Four times the lesser (4*2x) is (=)  12 less (-12) than twice the greater (2y)."

Doing it all in math, we get:

4(2x) = 2y - 12

This simplifies to:

8x = 2y - 12

And using the first equation (y=2x+2) we can substitute "2x+2" in for "y"  

8x = 2(2x + 2) - 12

Simplify the right side by first distributing:

8x = 4x + 4 - 12

Combine like terms on the right.

8x = 4x - 8

Subtract 4x from both sides

4x = -8

Divide both sides by 4

x= -2

Remember, our lesser even integer is 2x, so the lesser integer is 2*(-2)= -4, the greater is (-4)+2= -2.

Final answer:  The two consecutive even integers are -4 and -2.

To be even more fair I don't fully understand this completely either,... he explained it to me and I and getting it,... so anyway,... Hope it helps, and

Chow,...!

Answer:

Monomial is the expression that has maximum variable power 1.

so you can add any number or variable in the expression to make it monomial but the over power of variable must be 1.

Answer:

Domain: (-4, 4) Range: (0,4)

Step-by-step explanation:

Domain is the furthest left and right points on the x-axis while the range is the same but instead of it being the x-axis, it would be the y-axis. The graph shows -4 to 4 being the domain and 0 to 4 being the range.

Answer:

1/2

Step-by-step explanation:

3 is half of 6  so the smallest term would be 1/2.

Answer:

x = 11/5

Step-by-step explanation:

4x + 2 + 3x = 5 + 2x + 8

Combine like terms

7x+2 = 2x+13

Subtract 2x from each side

7x+2-2x = 2x+13-2x

5x+2 = 13

Subtract 2 from each side

5x+2-2 = 13-2

5x = 11

Divide each side by 5

5x/5 = 11/5

x = 11/5

Answer:

2.2

Step-by-step explanation:

4x+2+3x=5+2x+8

combine like terms

7x+2=2x+13

Subtract 2x from each side

5x+2=13

subtract 2 from each side

5x=11

Divide each by five

x=2.2

Answer:

51.35 mph to the nearest hundredth.

Step-by-step explanation:

The time she takes to travel 60 miles = distance / average speed

= 60/50 = 1.2 hours.

Total time taken =  1.2 + 2.5

= 3.7 hours.

Total distance travelled = 60 + 130

= 190 miles.

Therefore average speed for the whole journey

= 190 / 3.7

= 51.35135 mph.

Answer:

61

Step-by-step explanation:

(5 + 6i)(5 - 6i)

FOIL

first: 5*5 =25

outer: 5 *-6i = -30i

inner: 6i *5 = 30i

last: 6i * -6i = -36 i^2 =-36 (-1) = 36

Add together

25 -30i+30i+36

61

[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]

[tex] \sf \: ( 5 + 6 i ) ( 5 - 6 i )[/tex]

Multiply complex numbers 5+6i and 5-6i in the same way as you multiply binomials.

[tex] \dashrightarrow \sf 5\times 5+5\times \left(-6i\right)+6i\times 5+6\left(-6\right)i^{2} [/tex]

By definition, i² is -1.

[tex] \dashrightarrow \sf 5\times 5+5\times \left(-6i\right)+6i\times 5+6\left(-6\right)\left(-1\right) [/tex]

Do the multiplications.

[tex] \dashrightarrow \sf \: 25-30i+30i+36 [/tex]

Now cancel -30i & +30i

[tex]\dashrightarrow \sf \: 25 \: \bcancel{- 30i} \: + \: \bcancel{30i}+36 [/tex]

Now the equation becomes

[tex]\dashrightarrow \sf \: 25 \: + 36 \\ \dashrightarrow \boxed{\bf \: 61}[/tex]

Answer:

y = 17

Step-by-step explanation:

3x = y - 5, for x = 4

Answer:

y = -3x - 8

Step-by-step explanation:

[tex]y =\frac{1}{3}x+ 2[/tex]

Here slope m = (1/3)

Slope of the perpendicular line = [tex]\frac{-1}{m}[/tex] = -1 ÷ [tex]\frac{1}{3} = -1 *\frac{3}{1}= - 3[/tex]

Slope m1 = -3 and (-3 ,1)

Equation of line:

y -y1 = m(x -x1)

y - 1 = -3(x - [-3])

y - 1 = -3(x + 3)      

y - 1 = (-3) *x + 3*(-3)

y - 1 = -3x - 9

    y = -3x -9 +1

y = -3x - 8

Answer:

y = - 3x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x + 2 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then

y = - 3x + c ← is the partial equation

To find c substitute (- 3, 1 ) into the partial equation

1 = 9 + c ⇒ c = 1 - 9 = - 8

y = - 3x - 8 ← equation of perpendicular line

Answer:

∠BAC=70°

Step-by-step explanation:

If AB || CD and BC II DE that means the two triangles are congruent or the same, this means ∠BAC°=∠DCE°, ∠ABC°=∠EDC°, and ∠BCA°=∠DEC°. The three angles of a triagle add up to 180°. If ∠DEC=45° and ∠EDC=65°

Total°-(∠DEZ°+∠EDC°)=∠DCE° or ∠ECD°

180°-(65°+45°)=70°

∠BAC°=∠DCE°

Therefore ∠BAC=70°
