<em>if 5 is to be rounded off, then the rule is, if the next significant digit is equal or greater than 5 it adds up, other wise not..</em>
<em>In this case the next significant digit is 0 which is less than 5 so it will not be added up.</em>

Answer:
Company B is the better deal. Diego will save $31.5.
Step-by-step explanation:
First, find the area of the rectangle: 45*30=1350 sq.ft.
Next, find out how much it will cost for Company A: $3.9 for 2 x 5 ft (10 sq.ft)
Divide 1350 by 10 to see how many of their sod rolls will fit into his yard=135.
Multiply $3.9 by 135=526.5$
Do the same with Company B: $150 for 450 sq.ft plus $45 delivery.
Dived 1350 by 450 to see how many rolls= 3
Multiply $150 by 3= $450, then add $45= $495
Subtract Company B's $495 from Company A's $526.5= $31.5 <-how much Diego saved.
×≥ 26/7 is the answer.
hope it helps!

Step-by-step explanation:
Answer: x=8 or x=-2
Step-by-step explanation:
It would be the first option on the test.
You should subtract 25 on both sides to get this equation x^2-6x-16 in order to factor. There are three multiplication equations to get to the number 16 which is 1*16, 2*8, and 4*4. 1*16 wouldn't work since you would get either 17, 15 or -15, 4*4 would also not work since you would get +/-8 or 0, which would finalize our two numbers 2 and 8.
Since the c value is negative you would need to get one of your numbers negative which would be -8 since -8 + 2 = -6 which would factor out to (x-8)(x+2). Subtract -8 and 2 for each x values to get 8 and -2.
