<span>a2 + 6a</span> + 6a + 36
a • (a+6)
6 • (a+6)
(a+6) • (a+6)
Multiply (a+6) by (a+6)
The rule says : To multiply exponential expressions which have the same base,<span> add up their exponents.</span>
The product is therefore, <span> (a+6)<span>(1+1)</span> = (a+6)2</span>
Final result :<span> -1 • (a + 6)<span>2</span></span>

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
-4x - 2 ≤ 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 2 on both sides: -4x ≤ 12
- [Division Property of Equality] Divide -4 on both sides: x ≥ -3
Here we see that any number <em>x</em> greater than or equal to -3 would work as a solution to the inequality.
Answer:
y = - (17 - x)/9
Step-by-step explanation:
We gots a right triangle withe legs 8 and 15
remember if we got a right triangle with legs length a and b and hytponuse c then
a²+b²=c²
so
diagonal=c
so
8²+15²=c²
64+225=c²
289=c²
sqrt both sides
17=c
the diagonal is 17in
