I just had the question and the correct answer is 36.
C. I think I’m not totally sure but I think that’s right
Answer:
25%
Step-by-step explanation:
25% of 960 is 240. to find that we need to do...
0.25 x 960 = 240
add the percent increace to the 960.....
960 + 240 = 1,200
Hope this helped! Please mark as brainliest! Thanks!!
This is an odd problem. The length and width look like they should be interchanged. Anyway I'll solve it and we'll talk about the results.
(x +7) (x + 3) = 396
x^2 + 7x + 3x + 21 = 396
x^2 + 10x + 21 = 396 Subtract 21 from both sides.
x^2 + 10x = 396 - 21
x^2 + 10x = 375
x^2 + 10x - 375 = 0 This probably factors.
(x + 25)(x - 15)
x + 25 = 0
x = - 25 which makes no sense. Negatives do not describe room dimensions.
x - 15= 0
x = 15. this is fine.
x+3 = 15 + 3 = 18
x + 7 = 15 + 7= 22
Check
=====
Area = L * W = 18 * 22 = 496. It does check.
22 should be the length
18 should be the width.
