Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
Answer: $122.50
<u>Step-by-step explanation:</u>
In Out
8:00 12:00 = 4 hours
12:45 17:30 =<u> 4.75 hours </u>
Total 8.75 hours
8.75 hours x $14/hr = $122.50
Note: to subtract 12:45 from 17:30, borrow 1 hour from 17 and add 60 minutes to 30:
17:30 → 16:90
- 12:45 -<u> 12:45 </u>
4: 45
4 hours 45 minutes = 
= 4.75 hours
Hey!!
here is your answer >>>
let's find x first ,
2x + 48 = 180
2x = 132
x = 66!.
there is a right angle,
the angle below the right angle is also 90°
angle y would be ,
180 - (90+ 48)
180- 138
=> 42
answer is 42!.
if helped!. brainliest
They aren’t like terms became 5x^2y has an exponent
We could have the numbers
5x^2 and 5x and they wouldn’t be like terms because one has an exponent
