Answer:
- 174.825
Step-by-step explanation:
Change the divisor 57.2 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
-100000 ÷ 572 = -174.825
and therefore:
-10,000 ÷ 57.2 = -174.825
Both calculated to 3 decimal places.
Answer:
-1960
Step-by-step explanation:
The expression on the left expands to ...
(4x -7)² = (4x)² +2(4x)(-7) +(-7)² = 16x² -56x +49
Matching coefficients, you have ...
Then the expression c(b+a) evaluates to ...
49(-56+16) = 49(-40) = -1960
