Answer:
C
Step-by-step explanation:
Look at the coefficients in the expression: -3 and 12. The largest number that divides them both is 3. That means you can factor out either a 3 or a negative 3. Try 3.
3(-x - 4) is not on the list of answers. Also, it's unusual to factor out a value that leaves a negative coefficient on x.
Try factoring out -3.
-3(x + 4) is answer choice C.
Bonus
Because this is a multiple-choice question without a "non of these" option, you can solve the problem by expanding--multiplying out--the answers!
A. 3(x + 4) = 3x + 12 ...nope, not it
B. 3(x - 4) = 3x -12 ...nope, not it
C. -3(x + 4) = -3x -12 ...bingo!
Answer: 348in^2
Step-by-step explanation:
8 x 9 = 72
72 x 2 = 144in^2 (front and back)
8 x 6 = 48
48 x 2 = 96in^2 (sides)
9 x 6 = 54
54 x 2 = 108in^2 (top and bottom)
Total Surface area = 144 + 96 + 108 = 348in^2 (second option on picture)
The correct answer is -30 3/4
Answer: c. p+n=35, 0.01p+ 0.05n = 1.03
Step-by-step explanation: p= number of pennies, n = number of nickels. Given the total number of coins is 35, we have the equation p+n = 35.
She has total of $1.03. The equation for that would be 0.01p + 0.05n = 1.03
Solve both the equations to get the answer.
