Answer:

x = 35 degrees.

Step-by-step explanation:

These are 2 'same side' interior angles of a parallelogram whose sum is 180 degrees.

So we have th equation:

3x + x + 40 = 180

4x = 180 - 40

4x= 140

x = 140 / 4 = 35 (answer)>

HELP ME PLEASE I REALLY NEED THE HELP​
dedylja [7]

Answer:

Answer = 126 square inches

Step-by-step explanation:

Square area formula is Area = s^2    (replace the s with the side length)

Square area -->  Area = 4^2       Area = 16in

Parallelogram area formula is Area = h * b (replace h with height length and replace b with base length)

Parallelogram area --> Area = 3.5 * 10     Area = 35

Rectangle area formula is Area = w * h    (replace width and height)

Rectangle area --> Area = 12.5 * 6    Area = 75

Then add them all up  75 + 35 + 16 = 126 square inches

….."………….."……how do u do dis?
raketka [301]

Answer:

x = -25

Step-by-step explanation:

3 -  \frac{x}{5}  = 8

5(3 -  \frac{x}{5} ) = 5 \times 8

5 \times 3 - 5 \times  \frac{x}{5}  = 5 \times 8

15 - 5 \times  \frac{x}{5}  = 40

15 - x = 40

- x = 40 - 15

- x = 25

x =  - 25
