Answer
23.70
Proof
3Q+5+2-8-5=65 ~ Simplify
3Q-6=65 ~Cancel out the six
+6 +6 ~Add 6 to both sides since it is a 3Q=71 negative.
/3 /3 ~Cancel out the three.
Answer ~Divide both sides by 3
Q=23.66
Rounded Up
Q=23.70
I think it's B. because 4,310 divided by 72 is about 59. And 4,200 divided by 70 is 60.
Answer:
10 yd
Step-by-step explanation:
The length of the top is
6+4 = 10 yd
The bottom must be the same length
The given trinomial can be factored using the factorization method.
x² - 2x - 24
The middle term should be written is such a way that the sum of two terms is equal to the middle one and their product should be equal to the product of first and third term. So the above expression can be written as
= x² -6x + 4x - 24
= x(x-6) + 4(x-6)
= (x-6)(x+4)
Thus, (x-6)(x+4) is the factored form of the polynomial.
So the correct answer is option B
Answer:
Step-by-step explanation:
Your difference of perfect cubes formula is given as
and you have already correctly identified a as 
and b as 
. So we fill in the formula as follows:
and we simplify. Remember that
. It's important that you remember the rules.
Simplifying then gives us
That's it, so fill it in however you need to on your end. Learn the patterns for the sum and difference of cubes and it will save you a ton of headaches...promise!!
