The rules tell me to add the exponents. But I when I started algebra, I had trouble keeping the rules straight, so I just thought about what exponents mean. The " a6 " means "six copies of a multiplied together", and the " a5 " means "five copies of a multiplied together". So if I multiply those two expressions together, I will get eleven copies of a multiplied together. That is:
Answer:
x = -6

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
6 = -2x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 6 on both sides: 12 = -2x
- [Division Property of Equality] Divide -2 on both sides: -6 = x
- Rewrite: x = -6
It’s the last option, D. Adjacent means next to or adjoining, and 8 is a complementary angle to 7 (: hope this helps
The correct answer is D) it has two factors and the factor (5+y) has 2 terms.
The factors are what are multiplied to make the expression. In this expression, (5+y) and 8 are multiplied, so those are the 2 factors.
The factor (5+y) has two terms, 5 and y.
Answer:
Since ZE and ZF are vertical angles, they are congruent.
8x+8 = 2x+38
8 = 2x-8x+38
8 = -6x+38
8-38 = -6x
-30 = -6x
x = -30/-6
x = 5
