X^2 - 13 x = -36
add 36 to both sides
x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
Answer:C 5a^2 +70a +240
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
If there are 5 for every 6, then you divide 36 by 6 and then you get 6
Once you get that, multiply 5 by 6 and get 30
Answer:
513.24132
Step-by-step explanation:
None of the numbers are large enough to make the next number higher. Therefore that would just be your answer.
I think it'd be 10in. If you cut it into three parts, where the bottom is sectioned off from the other two rectangles, the two rectangles on the side both have an area of 3in, so together they'd be 6in. The rectangle on the bottom has a length of 4 and a width of 1, so it'd be 4in... add those together and get 10in. Hope this helps
