ANSWER AND EXPLAIN I’LL MARK BRAINLIEST GIVING 26 POINTS

Estimate (eye-ballin'): slightly less than (3, 3)

Calculation: (2.6, 3.2)

Step-by-step explanation:

Given:

4x + 3y = 20

y = 2x - 2

Sophia's strat is absolutely correct. She makes two equations into one. This is called "substitution":

- Insert y of 2nd equation as y in 1st equation:

4x + 3(2x - 2) = 20

**Remember to multiply the entire thing by 3**

4x + 6x - 6 = 20

**Solve for x**

10x - 6 = 20

10x = 26

x = 2.6

Now that we have x, just plug it into any equation (hint 2nd is easier):

y = 2(2.6) - 2

y = 3.2

COORDS: (2.6, 3.2)

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
