Answer: n = 9
Step-by-step explanation:
first, we calculate the first equation.
7^9 = 7^n
then, we set the exponents as equal.
9 = n
then, we simply swap the sides.
n = 9
Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm
The expression after performing the indicated operation written as trinomial is:
Step-by-step explanation:
Given
(x + 4)(x - 2) + 3x
We have to multiply (x + 4)(x - 2) and then add 3x to it
So,
Combining alike terms
