Which equation can be used to determine the base, b, of a triangle given the area, A?

The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Hope it helped you :)

Step-by-step explanation:

The equation of the area:

Solve for b:

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

(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.
