3:8 = 12:x so multiply 8 by 4 which is 32 so 3:8 = 12:32. The next one is 3:8 = x:48 So for this, you can multiply 3 by 6 to get 18:48 as your answer.

Hello!
To solve this we have to follow the order of PEMDAS
Parenthesis, exponents, multiplication and division, addition and subtraction

Parenthesis first

Exponents next
21 + 36 - 27 * 3
Multiplication and division from left to right
21 + 36 - 81
Addition and subtraction from left to right
57 - 81 = -24
The answer is C.-24
Hope this helps!
Answer:
B. (3x^2+4x-7)+2(3x^2+4x-7) Is your answer
Step-by-step explanation:
Answer:
A. 23+(6-1)x-3
B. 93
Step-by-step explanation:
a) Nth term = F + (N - 1) x D, where F=First term, N=Number of terms, D=Common difference
6th row = 23 + (6 - 1) x -3
= 23 + (5) x -3
= 23 + (-15)
= 8 - number of boxes in the top row.
b) Sum = N/2[2F + (N - 1) x D]
= 6/2[2*23 + (6 - 1) x -3]
= 3 [46 + (5) x -3 ]
= 3 [46 + -15 ]
= 3 [ 31 ]
= 93 - total number of boxes in the entire display.
Hope this helps! Its 3:25 AM for me too so I know how you feel.
