To solve for the value of x, it is easiest by isolating "x" to one side of the equation. This method is shown below:
-2x - 13 = 8x + 7
Adding 2x to both sides:
-2x - 13 + 2x = 8x + 7 + 2x
-13 = 10x +7
Subtracting 7 from both sides:
-13 - 7 = 10x + 7 - 7
10x = -20
Dividing both sides by 10:
10x / 10 = -20 / 10
x = -2

Answer:
yes, parallelogram ABCD is a square.
Step-by-step explanation:
Given information: ABCD is parallelogram with vertices A(0,4), B(2, 2), C(4,4), and D(2,6).
We need to check whether this parallelogram is a square or not.
The opposite side of a parallelogram are parallel and congruent. If the interior angles a parallelogram are right angles then the parallelogram is square.
Formula for slope:
Now, find the slopes of each side.
The product of slopes of two perpendicular line is -1.
The product of slopes of any two consecutive sides is -1. It means all interior angles are right angle.
Therefore, the parallelogram ABCD is a square.
Answer:
the fraction of the sheet of paper does he use is 1 ÷ 12
Step-by-step explanation:
The computation of the fraction of the sheet of paper does he use is shown below:
= Piece of construction paper × piece to make a flower
= 1 ÷2 × 1 ÷ 6
= 1 ÷ 12
hence, the fraction of the sheet of paper does he use is 1 ÷ 12
By my guess I would say
170+290=460 length
225+35=260 width
460•260=119,600 mi
