Start by expanding the left side of the equation: -2(4x-7) is equal to -8x + 14.
This brings you to -8x+14 = -8x + 14.
Now add 8x to both sides. This brings you to 14 = 14
Now subtract 14 from both sides. This brings you to 0 = 0.
Thus your answer is 0 = 0, which is a true statement.
Hope this helps.
Answer:
i think it's about 20 im not 100 percent sure :/
Step-by-step explanation:
Area of equilateral triangle = a^2/4 * √3 so side of triangle = a
but if area of equilateral triangle = area of square multiplied by √3 then area of square = a^2 / 4 so side of square = a/2
the ratio length of side triangle to length side of square = a: a/2 that means the side of triangle is doubled the side of square
answer
a) 2:1
Answer: its 180
Step-by-step explanation: length times width is the area. 15 times 12 is 180
Answer:
C) y=3
Step-by-step explanation:
4y squared - 7y = 15
4(3) squared -7(3)=15
4(9) -7(3)=15
39-21=15
15=15
