B. X^2-6x. =14
Half of -6 is -3 and -3^2=9 so add 9 to both sides
X^2-6x+9 = 14+9
(X-3)^2= 23
A. 4 . . . Yes. 52/4 = 13
b. 26 . . . Yes. 52/26 = 2
<em>c. 3 . . . . No. 52/3 = 17 and 1/3</em>
d). 13 . . Yes. 52/13 = 4
Answer:
There needs to be numbers for the variables.
Step-by-step explanation:
I don't think you can do that without having the variables.
Answer:
The width is 7 cm
Step-by-step explanation:
The volume of a cereal box is
V = l*w*h
6860 = 35 * w * 28
6860 =980 w
Divide each side by 980
6860/980 = w
7 = w
So basically here is the answer mate!
2x + 7y = 3-------------------------(substitute x's value here, i.e., x = -4y)
2( -4y ) + 7y = 3
-8y + 7y = 3
-1y = 3
y = -3------------------------( 1 )
Since x = -4y
= -4 ( -3 ) --------------------------( since we found the value of y)
= 12
Here is the answer for x = 12 , y = -3
