Can someone plz explain how to do this Algebra 1 A=1/2(a+b)h for h
Alex_Xolod [135]
<span>A=1/2(a+b)h for h.

First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h

You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.

2A = (a + b)h

Now divide both sides by (a+b).

2A/(a+b) = h

According to the graphs below, which statement is true?
Varvara68 [4.7K]

Answer:

The graph on the right is misleading

Step-by-step explanation:

The brand preference is 21 to 25, which shows a slight advantage for Brand B. The graph on the right requires you to mindfully read the y axis to infer that - if you wouldn't, you'd think that Brand B dominates Brand A.
