17. Subtraction. According to the order of operations, he should've done the exponent of 3 first.

18. He then did 15×2. According to the order of operations, he should've done the multiplication of 8×2, since, if there are only multiplication and/or division left, you work left to right. He isn't correct.

19. 16, I think, I did it in my head.

The length of a rectangle is 10m greater than the width. The area is 24m^2
Ivan

Answer:

length: 12m

width: 2m

Step-by-step explanation:

24 = a*w

a = w+10

then:

24 = (w+10)w

24 = w*w + 10*w

24 = w² + 10w

0 = w² + 10 - 24

w = {-10±√((10²)-(4*1*-24))} / (2*1)

w = {-10±√(100+96)} / 2

w = {-10±√196} / 2

w = {-10±14} / 2

only positive numbers:

w = {-10+14}/2

w = 4/2

w = 2m

a = w+10

a = 2 + 10

a = 12m

Check:

24 = 12*2
