Answer:
A
Step-by-step explanation:
2 and 11 are factors of 22
Answer:
16
Step-by-step explanation:
f(x) = 2x^2 + 4x + 10
f(-3) = 2(-3)^2 + 4(-3) + 10
f(-3) = 2(9) + (-12) + 10
f(-3) = 18 + (-12) + 10
f(-3) = 16
Answer:
9) x = 5
10) x = 4
Step-by-step explanation:
a^2 + b^2 = c^2
9) 6^2 + x^2 = 8^2
- 36 + x^2 = 64
- 36 - 36
_______________
x^2 = 28
Square root them
Squareroot x^2 is x
Square root 28 is 5.29 round is 5
so x = 5
*Correct me if im wrong*
10) 3^2 + x^2 = 5^2
9 + x^2 = 25
- 9 - 9
____________________
x^2= 16
Square root them
square root of x ^2 is x and square root of 16 is 4
so x = 4
Answer:
x=0.875
Step-by-step explanation:
2×+y=1
y=0.5
4×+2y=-1
4×+2.5=-1
1+2.5=4x
3.5=4x
x=0.875
