Answer:
3.7%
Step-by-step explanation:
(p)principal=$3400
(t)time=9months=9÷12year=3÷4year
(i)interest=$94.50
(r)rate=?
we have
r%=i/(pt)
r%=94.50÷(3400×3÷4)
r÷100=94.50÷2550
r=0.37×100
r=3.7
required rate is 3/7%
For number 7 it’s basically 4x3 and 4x6 and for number 8 it’s 4x7 and 2x7
For number 9 it’s 5x3, 5x6, 5x2
The expression for volume is l•w•h (length times width times height). For example, you could say:
Amber is filling a cube with sand. She wants to find out the volume of the box to find out how much sand she needs. She knows that the length is 7 inches, the width is 3 inches, and the height is 4 inches. What is the volume of the cube?
Answer: 
Step-by-step explanation:
We have the following polynomial:

This is a polynomial of the form
. Following this rule to expand it, we have:


Applying common factor
:

Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:

Answer:
