arianne is taking a geometry course and is working with the area of triangles. she knows the area and the height but needs to find the base. rearrange the following equation for b, where a is the area, b is the base, and h is the height of the triangle.
a = 1/2bh
b = 2a − h
b = 2a/h
b = 2a + h
b = 2ah

Step-by-step explanation:

∵ Area of a triangle,

Where,

b = base of the triangle,

h = height of the triangle,

For finding the formula for b we need to isolate b in equation (1),

For this divide both sides by

We get,

Hence, SECOND option is correct.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

d is correct
