<span>8(R + 6) - 2R,
8R + 48 - 2R,
The result is 6R + 48</span>
Start with <span>x^2 +14x = -24,
Find HALF the value of 14: 7
Square this: 49
Add 49, and then subtract 49: x^2 + 14x + 49 - 49 = -24 We have a
perfect square
Rewrite the quadratic as the sq. of a binomial: trinomial on
the left
(x+7)^2 = 25
Take the sqrt of both sides: x+7 = plus or minus 5
Then x = -2 and x = -12</span>
Answer:
D
Step-by-step explanation:
we can set up the equation as 15x = 15x^2
factoring we get
15x(x-1) = 0
So the solutions are when x are 0 and 1
this gives the coordinates
(0,0) and (1,15)
2 [-3x+2y=8]
6x-2y=-20
-6x + 4y = 16
6x - 2y = -20
2y = -4
y = -2
use the first eq (u can use any) then substitute the value of y
-3x + 2(-2) = 8
-3x -4 = 8
-3x = 12
x = -4
