F(a)=a^2-5a+7
F(a+h)=(a+h)^2-5(a+h)+7
=a^2+2ah+h^2-5a-5h+7
F(a+h)-F(a)=(2ah+h^2)/h
Factor out h, we will have h(2a+h)/h, the answer is 2a+h
Answer:
c. 50
Step-by-step explanation:
Answer:
because angles on a straight line add up to 180 degrees substract (180-110), step 2; you will get 70 degrees afterwards the angle y is perpendicular it's 90 degrees.step 3;add (90+70) you get 160 .step 4;then substract (180-160) you get your answer as 20 degrees
I think it’s the first one: 5-m
Answer: 10
use (PEMDAS)
P parentheses ()
E exponents
M multiplication • , () , x
D division
A addition +
S subtraction -
Explanation:
There are no parentheses.
There are exponents.
The multiplication is the exponents.
There is division.
There is addition and subtraction.
-how to solve-
First, do 2 to the second power and get 4.
Next, do 12-2+4 divided by 8.
Next do multiplication: there’s no more.
Next do division: you can’t do 4 divided by 8 so instead, do 12-2 = 10 plus 8.
Hope this helps!
