Answer:21x^2-16x-16
Step-by-step explanation:
(3x)(7x)+(3x)(4)+(−4)(7x)+(−4)(4) =
21x^2+12x−28x−16
21x^2−16x−16
An ice cream machine produced 44 ice cream per minute.
Now, after reconditioning it speeds up to 55 ice cream per minute.
=> 55 - 44 = 11
=> 11 / 44 = 0.25
=> 0.25 * 100% = 25%.
thus it increased it production to 25%.
Answer:
160
Step-by-step explanation:
60-24=36 left
24 x 8 = 192
36/2=18
9 x 12 =108
108+192=300
300-140= 160 euros profit
Answer:
Equivalent
Step-by-step explanation:
The sets are not equal since computer science is not the same as algebra.
Equal means exactly the same
Equivalent means they have the same number of items in them
If they are equal, they are equivalent
The student mixed the letters. If you swicth the order of the letters then the equation would be true. y=4x. So if you plug in all the numbers into the equation you get the correct value for why. For example 4×2=8, 4×4=16, and so on.
