= 2s² + 7s - 10s - 35 =

= 2s² - 3s - 35

Answer:

2s² - 3s - 35 {final answer}

Step-by-step explanation:

Let's find simplest form of equation,

→ (s - 5)(2s + 7)

→ 2s² + 7s - 10s - 35

→ 2s²- 3s - 35

Thus, the answer is 2s²- 3s - 35.

Answer:

Step-by-step explanation:

Answer: Interval notation: (−∞, 3) ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: x<3 or x≥−1. x < 3 or x ≥ − 1. .

The statement in the mathematical form will be x ≤ 3. Then the inequality in the interval notation will be [3, ∞).

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

x is less than or equal to 3.

Convert the statement into a mathematical inequality. Then we have

x ≤ 3

The statement "x is less than or equal to 3" in the mathematical form will be x ≤ 3.

Thus, the inequality in the interval notation will be [3, ∞).

Answer:

1007

Step-by-step explanation:

Divide the expression by two parts: the first one with all positive integer (the integer which can't be divided by two), 1+3+5+...2013 and the rest -2-4-6-...-2012

If you notice both parts are arithmetical sequences

Explore the first one 1+3+5...+2013

a1=1 d=3-1=2 an=2013

a1+d(n-1)=an

1+2(n-1)=2013

2(n-1)=2012

n-1=1006

n=1007

Sn=( 1/2)*(a1+an)*n= 0.5*2014*1007=1007*1007=1014049

-2+(-4)-...-2012

a1=-2

d=a2-a1= -4-(-2)=-2

a1+d(n-1)=an

-2+(-2)(n-1)=-2012

n=1006

Sn= (a1+an)/2*n=(-2-2012)/2*1006=-1007*1006

-1007*1006+1007*1007= 1007- the answer

The second mean

1-2=-1

3-4=-1

There are 2012/2=1006 couples and every of them has sum -1

-1*1006=-1006

-1006+2013=1007

Answer:

Width = 17

Length = 92

Step-by-step explanation:

Perimeter of rectangle = 2 (length + width)

let us take width be x

length = 7 + 5x

width = x

so let us put these value

2 (length + width) = 218

2 (7 + 5x + x ) = 218

2 (7 + 6x ) = 218

14 + 12x = 218

12x = 218 -14

12x = 204

x = 204/12

x = 17

Width = x

         = 17

Length = 7 + 5x

            = 7 + 5(17)

            = 7 + 85

            = 92

Answer:

Distance from zero.

Step-by-step explanation:

a good example would be this:

the absolute value of -8 is +8 because -8 is 8 units from zero on the number line.

with everything else, whenever you have a negative number and it's a negative integer, it'll always be negative, and whenever you're trying to switch from positive it'll always be plus.

Step-by-step explanation:

[tex]7y + 4x - 10 + 5y - 5 + x[/tex]

[tex]7y + 5y = (7 + 5)y = 12y[/tex]

[tex]12y + 4x - 10 - 5 + x[/tex]

[tex] = 12y + 5x - 15[/tex]

Step-by-step explanation:

We have V=A3/2

We know that A = 100cm2, so just plug the area into the equation:

V = 1003/2

= 1002/2 * 1001/2

= 100 * √(100)

= 100 * 10 = 1000 cm3

Therefore, the area is 1000cm3

Another way to solve the problem is to figure out what the side length is from the area. Since the area is 100cm2, and we know that area of a cube face is s2 (where s is the length of the side), we can figure out the side length first like this:

s = √(100cm2)

s = 10cm

Then we can calculate volume using V = s3 = 1000 cm3

Answer:

Step-by-step explanation:

Answer:

none.

Step-by-step explanation:

because FTP=ATJ,

P=A

J=F

The two triangles are not congruent. The correct answer is option A.

If two triangles are congruent, this means they are the same shape and the same size. By definition, all corresponding angles of two congruent triangles are congruent. Additionally, all corresponding sides of two congruent triangles are congruent.

In the image two triangles, ETP and ATJ are given. Angle F and angle J are equal due to the opposite angle property. Similarly, angle P and angle A are also equal by alternate angle property. But all the angles are not congruent.

Hence, the triangle FTP and ATJ are not congruent with each other.

Answer:

6. Not so clear

7. 72 degrees

8. 5x + 60 = 180

9. 15 degrees

10. C

Step-by-step explanation:

7. 4x + 12 + 3x + 4 = 121 So this is the equation for the whole angle ADC.

7x + 16 = 121 Collect like terms

7x + 16 - 16 = 121 - 16 Bring 16 to the other side of the equation

7x / 7= 105 / 7

x = 15

After finding the value of x substitute it into the equation for angle ADB thus:

4 ( 15 ) + 12 = 72 DEGREES

8. When those two angles meet they form an angle in a straight line thus they sum to 180 degrees.

9. So we already know of all angles except for 1 which is the one you need to find and what you simply do is:

Add 120 + 30 + 15 = 165

Then subtract 165 from 180 because they are angles in a straight line:

180 - 165 = 15 degrees

10. The answer is C because they are adjacent and they form a perpendicular.

-10+14=x+36

then subtract 14 from both sides of the equation

−-10x+14-14=x+36-14

then simplify it
