Answer: 54
<u>Step-by-step explanation:</u>
replace "a" with "-2" in the g-equation
g(a) = a² - 4a + 42
g(-2) = (-2)² - 4(-2) + 42
= 4 + 8 + 42
= 54
Answer:
We just add numerators and rewrite denominator.
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
Step-by-step explanation:
You mean unlike denominators and like denominators.
Adding like dominators: We just add numerators and rewrite denominator :
Example : 
Adding unlike dominators:
We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.
For example :

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

Hoped this helps! Just had it on a quiz and got it right. If you have boxex by 4 a^1 b^2
Answer:
<u>Width= 120</u>
<u />
Step-by-step explanation:
We know that <u>L*W= A</u>
So lets put in the variables we know into the equation.
<u>L= 132 yards</u>
<u>A= 15840</u>
132 * W= 15840
All we need to do is <u>divide 15840 by 132</u>
<u>15840/132= 120</u>
<u>W=120</u>
