20. A rectangle is eight inch long and its diagonal is ten inches. What's the width of the rectangle?
(A) 3 inches
(B) 6 inches
(C) 4 inches
(D) 5 inches

B

Step-by-step explanation:

In this case you would use the pythagoram theorem.

A^2+B^2=C^2

8^2+B^2=10^2

64+B^2=100

subtract 64

B^2=36

square root both sides

B=6

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
