Answers:
1. V=triangle area × length
V=1/2×8×12×20
V=960in³
2. triangle area × length
Area of the triangle=1/2×4×11
A=22ft²
V=22×6
V=132ft³
3. b, volume always have cubic power (³)
4. d, same reason of question 3
Answer:
Step-by-step explanation:
Take out 3x from both sides:
5x - 3x = 3x - 3x
2x = 0
2x + 9 = 1
Take out 9 from both sides:
9 - 9 = 1 - 9
0 = -8
Divide 2 from both sides:
Answer:
The GCF of 7 and 19 is 1.
Step-by-step explanation:

Answer:
On x it is 9, on y it is 37,49
Step-by-step explanation:
Answer:
-3/2
Step-by-step explanation:
One can read off the slope of the given line directly from the graph. As x increases by 3, y increases by 2. Thus, the slope of the given line is
m = rise / run = 2 / 3
Any line perpendicular to this given line has a slope which is the negative reciprocal of the slope previously found:
-1 3
Slope of perpendicular line = ------------ = - -----
2/3 2
This matches the first of the given possible answer choices.
