To find out the answer,we can test it out one by one:
The original expression: 6×(2+8)=60
A. 6x(8+2)= 6x10 = 60✅
B. (6×2)+8 = 24+8 = 34
C. (8+2)x6 = 10×6 = 60✅
D. 6x2÷6×8 =12÷6×8 = 2×8 = 16
As A. and C. equals to the original expression, the answer is A. and C.
Answer:
2x+7
Step-by-step explanation:
See the attachment for the working and an explanation of how you find the numbers in the table.
The quotient is 2x+7.
Answer:
Option A wilk be the correct answer.
f(x) = 3/(x + 2) - √x - 3
f(7) = 3/(7 + 2) - √7 - 3
f(7) = 3/9 - √4
f(7) = 0.333 - 2
f(7) = -1.67
Answer:
(x-7)(x+7)
Step-by-step explanation:
x^2 -49
This is the difference of squares
x^2 -7^2
We know that a^2 -b^2 = (a-b)(a+b)
(x-7)(x+7)
