Leilani hung a triangular pennant for her favorite baseball team in her room as shown below. If the area of Leilani’s pennant is 82.65 in.2, what is the measure of the base in inches?

Step-by-step explanation:

recall the area of a triangle is  Area = 1/2* Base* height

then we know the height, and the area solve for the base

I'll do the algebra symbolically so you can see how

A = 1/2 *B * H  ( start here)

2A/H = B   ( move to here )    

Now plug in what you know on the left side

2*82.65/17.4 = base

9.5 = base  :)

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
