First, you gotta simplify. There’s really nothing to simplify so just take it out of the parenthesis.
2x-8=2x-4
Now turn the -8 into a +8. Add it on each side.
2x=2x+8
Now turn the 2x on the right into a negative. Do the same thing you did with the 8.
Now it’s:
0 = 8
That means there’s no solution.
Hope this helped :)
Answer:
63.72 ft^2
128 cm^2
Step-by-step explanation:
5. The area of a triangle is
A = 1/2 bh where b is the base and h is the height
A = 1/2(21.6) * (5.9)
= 63.72 ft^2
6. The scale factor is 20/15 = 4/3
When we find area is the scale factor is squares
(4/3) ^2 = 16/9
Taking the ratio of the areas
A big trap
------------------- = scale factor squared
A little trap
A big trap 16
-------------- = ------
72 9
Using cross products
9A = 16*72
9A = 1152
Divide each side by 9
A = 1152/9
A =128
The area of the large trapezoid is 128 cm^2

Answer:
x = -6
Step-by-step explanation:
Subtract the right side, simplify, divide by the x-coefficient.
4(x -3) +54 +3x = 0
4x -12 +54 +3x = 0 . . . . eliminate parentheses
7x +42 = 0 . . . . . . . . . . combine terms
x +6 = 0 . . . . . . . . . . . . . divide by 7
x = -6 . . . . . . . . . . . . . . . add the opposite of the constant
Answer:
C
Step-by-step explanation:
Since we have a point and a slope, we can use the point slope formula.
The point slope formula is:
where m is the slope, and (x1, y1) is the point given.
We know that the slope is -3, and the point given is (10, -1)
Therefore, our m is -3, x1 is 10, and y1 is -1.
y- -1 = -3(x-10)
y--1 is the same as y+1
y+1= -3(x-10)
Therefore, choice C is correct.
