For this case we have the following expression:
36-12x + *
The value of * is given by:
36-12x + x ^ 2
Thus, we can rewrite the expression as a perfect square in the following way:
36-12x + x ^ 2 = (x-6) (x-6)
36-12x + x ^ 2 = (x-6) ^ 2
Answer:
The value of * is:
* = x ^ 2
Answer:
14 cm
Step-by-step explanation:
If the rectangle is 15 cm wide then the total width is 30.
So we can subtract 30 from 70,
=40
If the length is increased by 2 then there is 4 more cm added to the total length.
We can do, 40-4
=38
If 38 is the total length we do 38 ÷ 2
=14
<em>Thus,</em>
<em>The original length was 14 cm.</em>
Answer:
y=-13
Step-by-step explanation:
Plugging in -7:
y= (-7)2 + 1
-7 * 2 = -14
So:
y= -14 + 1
-14+1=-13
The answer is A.multiply 3 * 6 and 3.6 * 5 and see if cross products are equivalent
First, you gotta simplify. There’s really nothing to simplify so just take it out of the parenthesis.
2x-8=2x-4
Now turn the -8 into a +8. Add it on each side.
2x=2x+8
Now turn the 2x on the right into a negative. Do the same thing you did with the 8.
Now it’s:
0 = 8
That means there’s no solution.
Hope this helped :)
