Given A = 1/2 × b × h, when A = 75 and h = 10, find b.

b=15

Step-by-step explanation:

A=1/2×b×h

75=1/2×b×10

75×2÷10=b

15=b

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

f is the midpoint of
