4n-5 = 3n+2 thats taking the word problem and writing it out
Now solve
4n-5=3n+2
n = 7
Answer:
x = 5
Step-by-step explanation:
Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.
7x + 16 + 39 + 90 = 180
Simply.
7x + 145 = 180
-145 -145
7x = 35
/7 /7
x = 5
^-^
replace the numbers inside () for x
f(4) = -4(4)-3 = -16 -3 = -19
G(-4) = 2(-4)^2 -3(-4) = 44
