Answer:
16
Step-by-step explanation:
Given
f(x)=5x^2+9x-2
Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).
Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:
f(x)=5x^2+9x-2
f(-3) = 5(-3)^2 +9(-3) -2
=5(9) - 27 -2
= 45-29
= 16 !
I think answer is 9.3 after it’s rounded
use the formula a^2 +b^2=c^2
4-7x=5
+7x +7x
4= 12x
/12 /12
x= 4/12
x= 1/3
