Step-by-step explanation:
similar shapes means that they have the same angles, and there is one scale factor that applies to all sides and other lines in the shapes (like heights).
therefore the ratios between 2 correlated lines are all the same.
so,
2/7 = 5/height
2×height / 7 = 5
2×height = 7×5 = 35
height = 35/2 = 17.5 in
If the slice is made parallel to the base, then if the base is a rectangle, the cross-section would be A. rectangle
Answer:
I believe the answer is y = 2x+6 (A)
Step-by-step explanation:
Answer:
(3x - 5)(x + 1)
Step-by-step explanation:
We need to factor 3x² - 2x - 5.
In order to do this, we must look at the factors of 3 and -5:
3 = 1 * 3
-5 = 1 * -5
Somehow, we need to pair up these so that they add to -2. We realize we can do this by multiplying 1 by -5 and adding that to 1 * 3:
1 * -5 + 1 * 3 = -5 + 3 = -2
So, we have (3x - 5)(x + 1).
Slope of line = Y2 - Y1 / X2 - X1
= 0 - 8 / -1 - 3
= -8/-4
= 2
