Answer:
The equation simplified equals to 7
Step-by-step explanation:
Answer:
1 or 5
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 5x would be 5.
The coefficient of x^2 would be 1.
Hope this helps!
Answer:821,800
Step-by-step explanation:
Because the area of a trapezoid is A= ((a+b)/2)h, where a is the length of the top, b is the length of the base, and h is the height, you plug that in to find your answer.
This trapezoid is sideways, but the top of it is 7m (which is a) and the base is 10 m (which is b), add a and b to get 17, A = ((17)/2)h
Now divide by 2 to get A = (8.5)h
Because the height is 9, A = (8.5)9 = 76.5
The area of the trapezoid alone is 76.5m
Answer:
x = 12
WN = 28
Step-by-step explanation:
SO = WN and SO = 2WI
3x - 8 = 2(x + 2)
3x - 8 = 2x + 4
3x - 2x = 4 + 8
x = 12 now replace x with 12 in the first equation given
3x - 8 = 3×12 - 8
36 - 8 = 28
