Solve for a: a²-8a +12 is A. -2,-6 B. 2,6 C.-3,-4 D. 3,4

1 answer:

7 0

If you would like to solve the equation a^2 - 8*a + 12 = 0 for a, you can calculate this using the following steps:

a^2 - 8*a + 12 = 0
(a - 6) * (a - 2) = 0
1. a = 6
2. a = 2

The correct result would be B; 2, 6.

tamaranim1 [39]

Length should be 2/5yd:

18inch*1yd/36inch=.5yd=> depth

volume= 2(length*width+lenght*depth+depth*width)

let l to be the length.

volume= 2(l*2+2(.5)+.5*2)

volume=5l+2

4=5l+2

2=5l

l=2/5

The equation for a parabola has the form y = ax2 + bx + c, where a, b, and c are constants and a ≠ 0. find an equation for the p

sattari [20]

To solve the problem, substitute the given points for x in the given equation to get

$-10=(-1)^2a+(-1)b+c\Rightarrow-10=a-b+c \\ -6=(1)^2a+(1)b+c\Rightarrow-6=a+b+c \\ -13=(2)^2a+(2)b+c\Rightarrow-13=4a+2b+c$

Solving the three equations simultaneously, we have:

a = -3, b = 2 and c = -5

Therefore, the required equation is

$y=-3x^2+2x-5$
