Answer:
-12
Step-by-step explanation:
2(6a-2b)-8(-2)
=2[6(-1)-2(4)]+16
=2[-6-8]+16
=2[-14]+16
=-28+16
=-12
Answer:
2 x 5 = 10, 10 x 2 = 20
4 x 2 = 8, 8 x 2 = 16
5 x 4 = 20, 20 x 2 = 40
40 + 20 + 16 = 76 yd^2 is your answer.
Answer:
{ - 2, 10 }
Step-by-step explanation:
Given
x² - 8x = 20
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 20 + 16, that is
(x - 4)² = 36 ( take the square root of both sides )
x - 4 = ± 
= ± 6 ( add 4 to both sides )
x = 4 ± 6
Thus
x = 4 - 6 = - 2
x = 4 + 6 = 10
Answer: C
Step-by-step explanation:
x-3y=5, y=x-7 *solve it
the answer is (8,1)
so..
C. (8,1) is a solution to both equations so it is a solution to the system
Given:
h = 9 in
r = 1.5 in
Since volume of a cylinder is V = pi*r^2*h
V = pi*(1.5in)^2*(9in)
V = 63.6 cu in
The best and most correct answer among the choices provided by your question is the first choice or letter A. The vase can hold 63.6 cubic inches of water.
