Answer:
Formulas for a rectangular prism:
Volume of Rectangular Prism: V = lwh.
Surface Area of Rectangular Prism: S = 2(lw + lh + wh)
Space Diagonal of Rectangular Prism: (similar to the distance between 2 points) d = √(l2 + w2 + h2)
Step-by-step explanation:
Hope it helps :))))
Well that's easy. Just plug in the numbers: 3*(-2)+4*(5)=14. So yes the solution is correct.
Answer:
the value of x-1/x is given down
Step-by-step explanation:
=(x+1/x)²=x²+1/x²+2
=(5)²=x²+1/x²+2
=x²+1/x²=25-2
=x²+1/x²=23 this is the answer
if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer
Answer:
Length of arc AB = 4π
Step-by-step explanation:
Formula to get the arc length is given by,
Length of arc = 
Here, θ = central angle subtended by the arc AB
r = Radius of the circle
By substituting the values in the formula,
Therefore, length of arc AB = 
= 40π
6x +2y
Solution:
Given expression is (6x + 4y) –2y.
To find the equivalent expression for the given expression.
⇒ (6x + 4y) –2y
⇒ 6x + 4y –2y
Combine like terms together.
⇒ 6x + (4y –2y)
⇒ 6x + 2y
6x +2y is equivalent to (6x + 4y) –2y.
Hence, the expression equivalent to (6x + 4y) –2y is 6x + 2y.
