Answer:
180
Step-by-step explanation:
8 x 10 = 80
100 + 80 = 180
Its gonna be 229/12, u r gonna find the lcm of the 3 denominators which is 12 and complete the work
Answer:
17
Step-by-step explanation:
f(x)= -2x+7
f(-5)= -2(-5)+7
10+7
f(-5)=17
I think the answer is 17%
X²+3x-21=0
1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2
2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21
Answer: the product of the 2 solutions of this equation is -21
