Answer:
f(x)=x^2+3
f(x+y)=(x+y)^2+3
this is done by replacing x with (x+y)
f(x+y)=x^2+2xy+y^2+3
therefore : f(x+y)= x^2+y^2+2xy+3
Answer:
x=29°
Step-by-step explanation:
as lines are parallel.
external alternate angles are equal.
7x-86=4x+1
7x-4x=1+86
3x=87
x=87/3=29
Simplify 2/3 - 1/7 to 11/21
10/21 + 11/21
Simplify
The answer is 1.
Answer:
Step-by-step explanation:
f(x + 1) = 8(x + 1) + 1 = 8x + 8 + 1 = 8x + 9
