Answer:
x=35
Step-by-step explanation:
For a polygon with n sides, the sum of its interior angles is equal to
(n-2) * 180
Here, there are 6 sides, so the sum of this polygon's interior angles is equal to (6-2)* 180 = 720
Therefore, the sum of the interior angles is 720. We can add them up to get
(4x-5) + 117 + (3x-3) + (3x+6) + 118 + 4x-3
= 14x +230 = 720
subtract 230 from both sides to isolate the x and its coefficint
14x = 490
divide both sides by 14 to get x
x=35
2 2/5=12:5
5 1/5= 26:5
12:26:5
I think.
Answer:
10/2
Step-by-step explanation:
first 10/2=5
you divide 10 into 2 until you get 5 of such groups
You can basically just plug in the values. “1) (0,5) and (1,6)” is correct.
X^2+2x-63
(x+9)(x-7)
since x is squared, you immediately know that it multiples itself. (x)(x) is x^2. I used the FOIL method where you do first, outside, inside, last. so the first amount in each parentheses is a x and a x. that equals x^2. then the outside numbers are 7 and a x. That equals-7x. on the inside, I have +9 and x. that is +9x. Lastly, a -9 and -7 is -63. When written out in a number sentence, and combine like terms, you will get your original answer so (x+9)(x-7) is the factored form
