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
Answer:
what. omg what if is this
Answer:
Mr Adams worked for 52 hours in four days.
Step-by-step explanation:
To get 52, you divide 78 and 6 and get 13. 13 is how many hours he worked a day. Since we need to find out how many hours he worked for 4 days, we add 13 4 times. If we add, the equation would look like this: 13+13+13+13=52. We can multiply also since it's easier. If we multiply our equation would be 13×4. Therefore, Mr Adams worked 52 hours in four days. Hope this helped
Answer:
the answer is one over eight
the formula says required outcome divided by sample space
the sample space here is it because we have three coins and the Three coins have two faces each so it becomes 2 x 2 * 2 that is 8 and that is the total sample space we are supposed to get the probability of getting 3 tails and for each coin you have 1/2 x 1/2 x 1/2 and that is 1/8 as your final answer and do probability of getting three tails
Alternate interior= 2 and 6
Consecutive int.= 7 and 6
Corresponding = 1 and 3
Alternate ext.= 1 and 5
Vertical= 1 and 7
#41 = measuere 6 and 11 add up to 180, subtract 180 from 50 and you get 130
