X^2 + X - 12 = 0
(X + 4)(X - 3) = 0
X = -4 and X = 3.
The letter or symbol expresses an unknown value. There is no value to a letter or symbol.
Answer:
12 to 8, 6 to 4
Step-by-step explanation:
Answer:
144'
Step-by-step explanation:
Your ratio is 45'/5" or 9:1
9x4"=36'
9x3"=27'
45+36+36+27=144'
I believe this is the same answer as I gave previously.
Answer:
Step-by-step explanation:
Let's do the obvious things first.
Right rectangle
w = 11
L = 17
Formula
Area = L * W
Area = 11 * 17
Area = 187
Left rectangle
W = 8
L = 11
Area = 8 * 11= 88
Middle Rectangle
W = 11
L = 15
Area = 11 * 15 165
Now we come to the triangles. It's not obvious what to do with them. You have to infer that one of the lets is 8 and the other is 15. You get the 8 from the width of the left rectangle (see above.)
There are 2 triangles
Area = 2 * 1/2 * l1 * l2
Leg 1 = 8
Leg2 = 15
Area = 2 * 1/2 (8 * 15)
Area = <u> 120 </u>
Total = 120 + 165 + 88 + 187 = 560
Unless you have an E answer that is 560, my answer does not agree with any of the given answers. I would suggest that you ask your teacher how it is done. My method is correct.
