Answer:
15 and 108
Step-by-step explanation:
3*(30-25)=3*5=15
4*(12+15)=4*27=108

Answer:
The second option
Step-by-step explanation:
For this problem, there are multiple ways to solve. The easiest here is the cross method. For ax²+bx+c, you find 2 numbers that multiply to ac and add to b, which you replace b with.
ac in this case is -8×3, which is -24. b in this case is 23.
You can go through the factor pairs of -24 to find the ones that add to b. These pairs are (1 and -24, -1 and 24, 2 and -12, -2 and 12, 3 and -8, -3 and 8, 4 and -6, -4 and 6). The only pair that adds to 23 is 24 and -1.
You sub this into the original equation, making 3x²+24x-x-8.
From there, you factorise, making 3x(x+8)-x(x+8).
This can be factorised further to (3x-x)(x+8) by collecting like terms.

Answer:
2.86$
Step-by-step explanation:
first you must find out how much she is spending since she is buying 2.8 pounds of asparagus that are 2.55 per pound you can just times 2.8 x 2.55 its the same as if it were a dollar for a pound it would be 1 x 1 except in the case of this question it is a decimal number. Now that you know how much she spent you would subtract it from 10 since that's the amount she gave the cashier so you subtract the cost from how much she gave and you will get how much change she will get.
