Answer:
a(5
b)30
Step-by-step explanation:
in the first one you divide 25 by 5
in the second one you multiply 6 times 5
A. 2/5
B.2/5
C. The slope of ABC and AGH are equal
Answer:
B.
Step-by-step explanation:
First convert the equation to slope-intercept form:
2x - 5y = 7
-5y = -2x + 7
y = 2/5 x - 7/5
So the slope of the given line is 2/5.
So the slope of a perpendicular line will be -1/ 2/5 = -5/2.
Take B:
5x + 2y = 3
2y = -5x + 3
y = -5/2.
So its B.
The total surface area of this prism is 480.
