Answer:
27
Step-by-step explanation:
a + b = 7
a - b = 3
2a = 10
a = 5
b = 7 - 5
b = 2
3⁵ / 3² = 3³ using law of indices
3³ = 27.
Answer:
2x + 12
Step-by-step explanation:
Example of Associative Property Addition:
a + (b+c) = b + (a+c)
Now, implement it to the given expression:
(2x+8) + 4 = 2x + (8+4)
That simplifies to:
2x + 12
Divide 395 by 4 then you get the answer 98.75 for each length.

Answer:
Step-by-step explanation:
<em>4 : 6 = 2/3</em>
<em>8/3 : 4 = 2/3</em>
<em>16/9 : 8/3 = 2/3</em>
Answer:
f(-2) = 90
Step-by-step explanation:
Plugging in the value of f(x) into the equation:
f(-2) = 5(-2)3^(-2)
f(-2) = 5(-2)(-9) - evaluate the power first
f(-2) = 90 - multiply from left to right to obtain answer
