11 cheap strategy. if f(x) = x^2 + 7, what is the value of f(3)?

f(3) = 16

Step-by-step explanation:

f(x) = x^2 + 7

Let x= 3

f(3) = 3^2 +7

Exponents first

f(3) = 9+7

f(3) = 16

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
