Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e. 
is the same
as taking the square root.
- so
is the same as the square root of 
.
For example, taking the square root of 4 will determine:
so the expression becomes
∵ 
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
The correct answer should be approximately letter b) 16x+32y=144 x+y=7
M²+ 12m + 36
m² + 6m + 6m + 36
(m+ 6)(m + 6)
B. (m + 6)²
Answer:
-x^2 + 21x + 3.
Step-by-step explanation:
9x - (x – 3)(x + 1) + 10x
= 19x - (x^2 - 2x - 3)
= -x^2 + 2x + 19x + 3
= -x^2 + 21x + 3.
Answer:
1468 in³
Step-by-step explanation:
First get get the total volume of the rectangular prism:
length l = 10 in
width w = 15 in
height h = 10 in
diagonal d = 20.6155281 in
total surface area Stot = 800 in²
lateral surface area Slat = 500 in²
top surface area Stop = 150 in²
bottom surface area Sbot = 150 in²
volume V = 1500 in
Now get get the volume from the missing rectangular prism:
ength l = 4 in
width w = 4 in
height h = 2 in
diagonal d = 6 in
total surface area Stot = 64 in²
lateral surface area Slat = 32 in²
top surface area Stop = 16 in²
bottom surface area Sbot = 16 in³
volume V = 32 in³
So 1500in³- 32 in³ =1468 in³
