Answer:
62) vertex (-1,-4) x intercepts are (1,0) and (-3,0)
63) vertex (4,-4) x-intercepts are (6,0) and (2,0)
64) vertex (-3,-4) x-intercepts are (-1,0) and (-5,0)
65) vertex (-4,-1) x-intercepts are (-3,0) and (-5,0)
Step-by-step explanation:
This is a way to work it out
Answer:
3x^2-8x-3y
Step-by-step explanation:
combine like turms and rearrange
The absolute error is 4 cubic inches. To find the absolute error, you simply subtract the two values.
The percent error is 10%. To find the percent error, we create a fraction out of the error and the actual value.
4 / 40 x 100 = 10%
Let's say the second piece is x ft long
The first piece is 2x ft long
The third piece is x+4 ft long
All of the pieces should add up to 10ft
x+2x+x+4=10
4x= 6
x=1.5ft
The first piece is 2x ft long=3 ft long
