SA = 2s^2 + 4sh
= 2(3^2) + 4(3)(6)
= (18) + (72)
SA = 90

hope this helps :)

torisob [31]

The installation fee is a one time thing so you do 375-50. and then you do 325/25 to get 13 so the answer is 13 months

Y=x2−6x+10<br> y=4−x<br><br><br> How do I substitute?

Shtirlitz [24]

Answer:

(2,2) and (3,1)

Step-by-step explanation:

Since we're given the value of y in the second equation, we can replace the y on the left side of the first equation with 4-x, giving us

$4-x=x^2-6x+10\\0=x^2-5x+6$

We can factor the expression on the right to get us

$0=x^2-5x+6\\0=x^2-3x-2x+6\\0=x(x-3)-2(x-3)\\0=(x-2)(x-3)$

Solving $x-2=0$ and $x-3=0$ gets us the solutions $x=2,3$ , which we can plug into the second equation to get us

$y=4-2=2\\y=4-3=1$

So, our solution set is the pair of points (2,2) and (3,1)

I really need help on this please help

Delvig [45]

I believe the X numbers are divided by 2, to get the Y numbers. So the blank X box is 1 and the other is 12.
