X^2 + 16x + ?
a^2 + 2ab + b
(a + b)^2 which is a perfect square.
To find b to determine the last value, you divide 16x by 2x.
so:
b = 8
the last value would be 8^2 which is 64.
Hence answer is C - 64
<span>F(x)=5x+3;g(x)=6x-5 find f/g(x) </span>
Answer would be {<span>x|x∈R</span>}
Answer:
a. 80.25
b. 104
Step-by-step explanation:
For (a), you add all the numbers together and divide by 4 because there are 4 test scores.
87 + 92 + 63 + 79 ÷ 5 = 80.25
For (b), we need to set up an equation. It is going to be a similar concept.
87 + 92 + 63 + 79 + x ÷ 5 = 85
x = 104
Hope this helps!
