the answer is 15 loads of gravel because 3 times 2 equals 6 which means 3 * 5 is equal to 15
Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
Answer:
13
Step-by-step explanation:
16*26 = 416
Converting fl oz to quarts is x/32
16/32 = 0.5 quarts
416/32 = 13
The value of the expression 2n - 1 when n = 7 is 13.
<h3>Equation</h3>
2n - 1
when n = 7
- Substitute n = 7 into the equation
2n - 1
= 2(7) - 1
= 14 - 1
= 13
<h3>What is mathematical expression?</h3><h3 />
Mathematical expression is an expression which involves the combination of numbers and variables in a valid way, in a function of addition, subtraction, multiplication, division and exponentiation
Therefore, the value of the expression 2n - 1 when n = 7 is 13.
