Lara and her brothers are painting a wall. Lara paints 2/8 of the wall.
Chuck and Max each 3/8 paint of the wall. How much of the wall do they paint all together?
Enter your answer in the box.

of the wall

2/8 + 3/8 +3/8 = 8/8

They finished the wall

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
