PLEASE HELP PLEASE IM STUCK PLEASEEE

Step-by-step explanation:

since it's a square we know the two sides are equal.  So set them equal and solve for X

a)

4x + 3 = 3x +17

4x-3x = 17 -3

x = 14

Since we now know X  plug it into the expression for the angle

b)

5(14) + 4y = 90    ( 90°  b/c we know the angle is equal to that )

70 4y = 90

4y = 90-70

4y = 20

y = 20/4

y = 5

c)

we can find the perimeter by just plugging in X to either of the expressions for the side and then multiplying that by 4,  since there are 4 sides

4(14) +3

56 +3

59

now times 4 for each side

59*4= 236

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
