Is your question true or false?
2abc - 3ab = -30? if a =2, b = -3 and c= 4
plug in
2(2)(-3)(4) - 3(2)(-3) = -30
Simplify
-48 + 18 = -30
-30 = -30
Both sides are equal so
It's true.
The volume of a rectangular prism can be found using the formula V = WHL.
W is the width, H is the height, and L is the length.
V = 512×612×12
V = 3,760,128
The volume of the bin is 3,760,128
Answer:
m<BAC = 60°
Step-by-step explanation:
Theorem:
In a triangle, the measure of an exterior angle equals the sum of the measures of its remote interior angles.
m<ACD = m<A + m<B
130° = m<A + 70°
m<A = 60°
m<BAC = 60°
Answer:
Median = 45
Step-by-step explanation:
Since the given data set is already in ascending order, we we just have to find the middle most number of the data set:
There are 2 middle numbers 40 and 50, so to find the middle most number find their average:
(40 + 50) / 2 = 45
Median = 45
Hope this helps!
Let's treat that one as a 4 by 8 rectangle with a 2 by 4 right triangle chopped out of the corner.
A = 4×8 - (1/2)×2×4 = 32 - 4 = 28
Answer: 28
