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.
The answer is 3 blocks per minute, because 30 divided 10 = 3.
Answer: B x=+-2
Step-by-step explanation:
The Quadratic formula is -b+-
First make everything equal to 0

Then Simplify

Now use the formula where a=3, b=0, and c=-12
divided by 2(3)


then we get 12/6 and -12/6 which simplified is +-2
Answer:
4x+14
Step-by-step explanation:
we know that in a rectangle, 2 sides are equal to one another (opposite sides), and the other 2 are equal to each other.
so,
2(5x+5) for the first 2 sides. you'd get 10x+10
2(2-3x) for the other two sides. you'd get -6x+4
add them up, and you'd get 4x+14
