Given m||n, find the value of x.

(7X+7)
(2x+2)
Answers
The value of x is 21.
From the attached diagram we can observe that the lines m and n are parallel to each other and these parallel lines are intersected by transversal t.
Let us assume that angle 'y' be a linear angle with (2x + 2)
(Both angles are below line n)
⇒ y + (2x + 2) = 180° .............(1)
So that, angles (7x + 7) and angle y are alternate exterior angles.
We know that alternate exterior angles are equal.
⇒ (7x + 7) = y
From equation (1),
(7x + 7) + (2x + 2) = 180°
9x + 9 = 180
9(x + 1) = 180
x + 1 = 20
x = 21
This is the required value.

I hope this helps!
Answer:
= 6x +9
Step-by-step explanation:
1. you need to multiply -3 by x² + 2x - 3
so you got -3x² -6x + 9
2. Then, you need to multiply 3 by (x²+4x)
= 3x² + 12x
3. -3x² - 6x + 9 + 3x² + 12x
4. then you need to solve with the same
= - 3x² + 3x²
= 0
= - 6x + 12x
= 6x

The perimeter of a rectangular tray is 28 inches. The length of the tray is 2 inches longer the width of the tray. Determine the dimensions of the rectangular tray.
Answers
Step-by-step explanation:
perimeter=28
length=2x
width=x
28=2(x+2x)
28=2x+4x
28=6x
28/6=6x/6
4.67=x
width=4.67
length=2×4.67
=9.34
Using the concept of perimeter of a rectangle, we have that:
The length is of 8 inches.The width is of 6 inches.------------------------------
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
[tex]P = 2(l + w)[/tex]
------------------------------
The perimeter is of 28 inches, thus:
[tex]P = 28[/tex]
[tex]2(l + w) = 28[/tex]
Dividing both sides by 2:
[tex]l + w = 14[/tex]
------------------------------
The length is 2 inches longer than the width, thus:
[tex]l = 2 + w[/tex]
Replacing into the equation, we find the width:
[tex]2 + w + w = 14[/tex]
[tex]2w = 12[/tex]
[tex]w = \frac{12}{2}[/tex]
[tex]w = 6[/tex]
The width is of 6 inches.
------------------------------
The length is:
[tex]l = 2 + w = 2 + 6 = 8[/tex]
The length is of 8 inches.

How do i find the x and y intercepts for x^2+y^2=20?
Answers
To find x-intercepts, set y=0 and solve for x.
To find y-intercepts, set x=0 and solve for y.
That will always be true (at least on x-y graphs).
x²＋0＝20
x²＝20
x＝±2√5
「y intercept」
0＋y²＝20
y²＝20
y＝±2√5

You will take a screenshot of your work when you are through, so be sure to clearly label your construction as you work.
Plot points A, B, and C, and draw a polygon, ΔABC, through the points.
Draw a line perpendicular to AC¯ through point B.
Label the intersection of the line perpendicular to AC¯ through B and AC↔ point D.

Can someone help me with this proportion? I'm really bad at math:
'Jill burns 200 calories in a 3/4 hour workout. How many calories will she burn in a 3 hour workout?'
Answers
Answer: 800 calories
Step-by-step explanation:
Let us set this up as a fraction
Firstly, convert 3/4 into a decimal
[tex]3 \div 4 = 0.75[/tex]
Now we can set up the fraction
Make sure to put the calories on the same side and hours on the same side as well. So it should be: [tex]\frac{200}{0.75}=\frac{x}{3}[/tex]
Then, solve
[tex]\frac{200}{0.75}=\frac{x}{3}[/tex]
The fractions are supposed to be proportional meaning, if the denominator is a certain number when solved, the numerator should be the same, if solve likely. let me show you:
Divide 3 by 0.75
[tex]0.75 \div 3 = 4[/tex]
Now since the number isn't found yet, we will use the opposite operation, which is multiplication, in this case.
Multiply 200 to 4
[tex]200 \times 4 = 800[/tex]
Therefore, she will burn 800 calories in a 3-hour workout.
