Answer:
We conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:
- Two more than 9 times a number, r.
- 9 times a number, r, increase by 2.
Step-by-step explanation:
Given the algebraic expression
9r+2
We know that 9r is the product of 9 and 3.
Thus,
9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.
or it can be also verbally expressed such as:
9 times a number, r, increase by 2.
Therefore, we conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:
- Two more than 9 times a number, r.
- 9 times a number, r, increase by 2.
Answer:
A
Step-by-step explanation:
(x-4)^2=5
(x-4)(x-4)=5
x(x-4)-4(x-4)=5
distribute
x^2-4x-4x+16=5
combine like terms
x^2-8x+16=5
move terms to the left and combine
x^2-8x+11=0
use the quadratic formula and simplify
x=-(-8)+/-2 to the square roots of 5 over 2
separate and solve
x=4+ square root of 5
x=4- square root of 5
ANSWER: x=4+/- square root of 5
Answer:
200 minutes
Step-by-step explanation:
14 + 0.09 x = 18 + 0.07 x
0.09 x - 0.07 x = 18 - 14
0.02 x = 4
x = 400/2 = 200
