Answer: I’ll give you an example of how to do it by solving number 9 - h^2 + 8h + 16
Step-by-step explanation:
Step 1: Find two numbers that when you multiply them it gives you the first term’s coefficient multiplied by the last term’s coefficient (1x16 = 16) and when you add them it gives you the second term’s coefficient (8). The numbers in this case are positive 4 and positive 4.
Step 2: Create two parenthesis with the letter accompanied by the numbers. (h + 4)•(h+4). And that’s how you factor.
In case the first term is elevated to the third you will have to take out GCF (greatest common factor) first. If the numbers are too high like in the exercise number 15 you can also take out GCF and it will make it a lot easier to solve. Sometimes what you write on the parenthesis in the step 2 can be simplified, if that’s so then you would have to do it in order to get the correct answer.
Hope this helps you.
Answer:
C) 7 and 3
Step-by-step explanation:
2x+4+8x-10=x²+15
10x-6=x²+15
0=x²-10x+21
0=(x-3)(x-7)
x=3 and 7
Given:
Area = 36 1/4 = 36.25 ft^2
Length = 8 3/4 = 8.75 ft
Unless this is a trick question, where the length can be found in the given values of the problem (where the answer would simply be L = 8.75ft), let us solve for the missing measurement, which is the width. A rug is rectangular, so to obtain the width, the area must be divided by the length. This is shown below:
Width = Area / Length
Width = 36.25 / 8.75
Width = 4.14 ft.
Answer
I assume you're talking about 6-7, so on the left lines, you already did it, you just regularly subtract the numbers, and then on the right lines, you round the first problem to the nearest ten, remember five and up, round up, so for question 6 the new number model would be 90-40=50. since 93 rounds down to 90 and 38 rounds up to 40. continue to do that and write the entire model AND answer on the line to the right. hope this helps
