Answer:
90
Step-by-step explanation:
Evaluate x^2 + 2 x^2 + 3 x^2 + 4 x^2 where x = 3:
x^2 + 2 x^2 + 3 x^2 + 4 x^2 = 3^2 + 2×3^2 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×9
3^2 = 9:
9 + 2×9 + 3×9 + 4×9
2×9 = 18:
9 + 18 + 3×9 + 4×9
3×9 = 27:
9 + 18 + 27 + 4×9
4×9 = 36:
9 + 18 + 27 + 36

Answer:1,3,4
Step-by-step explanation:
Answer:
C. Determine how many feet −55 feet is below zero feet.
D. Determine how far −55 is from zero on the number line
Step-by-step explanation:
Determine how many feet −55 feet is below zero feet.
This will give us the answer of 55feet , and the absolute value of -55 is 55.
0--55= 0+55 = 55
Determine how far −55 is from zero on the number line
This will also give me us 55 feet because the distance from 0 to -55 is 55
I.e. 0--55= 0+55 = 55
Answer: 55
Step-by-step explanation: The inside measure of a triangle should be 180 so knowing this subtract 43 and 82 and you get 55.
