Answer:
~ -4x+4y+10
Explanation:
~ We have to collect like terms such as all the x’s, y and the normal numbers.
~ Then add like terms together: x-5x, 4y plus nothing, 3+7
~ After adding them, you should get -4x+4y+10.
Answer:
Step-by-step explanation:
If you don't consider how the wood might be cut, or how the tray might be assembled, you can look only at the area requirements.
A tray that is 10.5 inches square will have an area of ...
(10.5 in)^2 = 110.25 in^2
That base will have a perimeter that is 4×10.5 in = 42 in. If the perimeter piece(s) are 2 inches high, the area of the sides of the tray will be ...
(42 in)(2 in) = 84 in^2
Then the total area of wood required for the proposed tray is ...
110.25 in^2 +84 in^2 = 194.25 in^2
__
The area of the wood Stephan has is ...
A = LW = (18 in)(12 in) = 216 in^2 . . . . . . more than required
__
Stephan <u>does</u> have enough wood to make the tray, because he has <u>216</u> square inches, which is <u>more</u> than he needs to make the tray, <u>194.25</u> square inches.
M= -7/27
I think that's correct
Answer:
-8 and -3
Step-by-step explanation:
Add 11x to both sides;
x + 3 = 0
Subtract 3 from both sides;
x = -3
x + 8 = 0
Subtract 8 from both sides;
x = -8
