Answer:

I would honestly choose 9

Step-by-step explanation:

Because it is using cross products and you want them to equal the same, so you take 6 x 12= 72 so you take 8 and multiply by each number Each time you know 72 x 8 wont work and the 576 wont work and that .75 is going to be way too little therefore its 9 and you can check by multiplying 8 x 9= 72

Solve for a. 5a−5−15=3a+6+4

taurus [48]

Answer:

Step-by-step explanation:

5a - 5 - 15 = 3a + 6 + 4 combine like terms

5a + (-5 - 15) = 3a + (6 + 4)

5a - 20 = 3a + 10 add 20 to both sides

5a = 3a + 30 subtract 3a from both sides

2a = 30 divide both sides by 2

a = 15

A parallelogram has an area of 300 square kilometers and a height of 20 kilometers. What is the length of the base?

Neko [114]

Answer: the length of the base is 15 kilometers.

Step-by-step explanation:

formula : Area of parrallelogram = Length of base x height

Given: Area of parallelogram = 300 square kilometers

height = 20 kilometers

Substituting values in the formula , we get

300 = Length of base x 20

Length of base = $\frac{300}{20}$

= 15 kilometers

Hence, the length of the base is 15 kilometers.
