Answer:
d 125
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let x be the supplement to the 55 degree angle
55+ x =180
Subtract 55 from each side
55+x-55 =180-55
x = 125

Answer:
It will take 4.71 hours to travel a distance of 221.43 miles
Step-by-step explanation:
Given
Distance covered in time 7.99 hours is 375.32 miles.
Now we know that speed is equal to distance per unit time.
Therefore,
Which is the constant speed, hence now time taken for a distance of 221.43 miles will be
Therefore, the time taken to cover 221.43 miles is 4.71 hours.
Answer:
brainiest? 37.68
Step-by-step explanation:

12 x 3.14 = 37.68
ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization
