Answer:
- left box: 25/36
- right box: 5/6
Step-by-step explanation:
If you square the binomial (x -a), you get ...
(x -a)² = x² -2ax +a²
Comparing this to your equation, you find that ...
-2a = -5/3 . . . . . . the x-coefficient
a = (1/2)(5/3) = 5/6
So, the number in the right box is 5/6, and the number in the left box is its square, (5/6)² = 25/36.
Filling these in, the equation reads:
x² -5/3x +25/36 = (x -5/6)²
__
That is, the constant in the squared binomial is half the x-coefficient.
Answer:
7+5x
Step-by-step explanation:
2+5
+5x
you need to add them to get 7 then just add the 5x
Each multiple choice question would be 5 points. For Louann she got 14 of the questions correct so 5 x 14 = 70 and 70 + 24 would be 94. For Carla she got 16 of the questions correct so 5 x 16 = 80 and 80 + 14 = 94. You're answer would be 5, hopefully this helps :)
X/(x+2) = (x+2)/(x+5)
(x+2)^2 = x(x+5)
x^2 + 4x + 4 = x^2 + 5x
x = 4
