Answer:
48 in³
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = 
× area of base × height
here area of base = 24 and height = 6, so
V = × 24 × 6 = 8 × 6 = 48 in³
Answer:
Which i think is the first one, there may just be a typing error.
Step-by-step explanation:
A polynomial of order n has the following format:
In which a is the leading coefficient, 
are the roots.
If a root appears m times, they are said to have multiplicity m.
Leading coefficient of 1 and roots 21 and 31 with multiplicity 1
So the correct answer is:
Which i think is the first one, there may just be a typing error.
Answer:
40
Step-by-step explanation:
all those numbers added equals 37.21
front end estimation is where you round to the first number on the left just ignore the decimal point in this case. so the answer would be 40
Answer:
-13a^2 + 170ab - 13b^2.
Step-by-step explanation:
1. 36(a+b)^2 - 49(a-b)^2
This is the difference of 2 squares: a^2 - b^2 = (a + b)(a - b).
36(a+b)^2 - 49(a-b)^2
= (6(a + b) + 7(a - b))( 6(a + b) - 7(a - b))
= (6a + 7a + 6b - 7b)( 6a - 7a + 6b + 7b)
= (13a - b)(-a + 13b)
If you require the expansion of this it is:
-13a^2 + 170ab - 13b^2.
Answer:
A. -0.875
Step-by-step explanation:
Find where the points are located
A=-4.25
B=2.5
Add the points
-4.25+2.5=-1.75
-1.75/2=-0.875
