Answer:

-13

Step-by-step explanation:

This is just a matter of simplifying.

x = 8-(-4)^2-5

Let's get rid of the exponent.

x = 8 - 16 - 5

x = -13

You can check if this is correct.

The tricky part is the -(-4)^2.

You have to solve the -4^2 first, instead of the parenthesis.

abruzzese [7]

Cassava = 1/3 of his land

Remaining after planting Cassava = 1 - 1/3 = 2/3 of his land

Maize = 2/5 x 2/3 = 4/15 of his land

Vegetables = 2/3 - 4/15 = 2/5 of his land

If vegetables = 10 acres

2/5 of his land = 10 acres

1/5 of his land = 10 ÷ 2 = 5 acres

5/5 of his land = 5 x 5 = 25 acres
