Answer:
39
Step-by-step explanation:
Total interior angle of a triangle equal to 180. [180-102]/2
Answer:
8
Step-by-step explanation:
12 times x (the first square) is equal to 16 times x-2 (the second square)
Distributed
Simplified (divided by 16)
Subtract x from both side of the equation
Both negatives cancel each other out
0.25 times what equals 2,...
Hope it help,... and I'll see you in life,... well not really, but you get the idea,... Chow,...!
First you need to get a common denominator. The first two problems already have a common denominator, so you just have to find the sum and difference of the two problems, respectively.
6.) (9y-3)/(y^2-5)
8.) 3/xy^3
Two find a common denominator, find the smallest value that has BOTH denominators as factors.
10.) 8x^3*y^3 is the common denominator
Answer: 2/(8*x^3*y^3)
12.) Factor x^2 + 4x + 4 to get (x+2)(x+2)
Therefore, x+2 is already part of x^2 + 4x + 4
(x+4)/(x^2+4x+4)
14.) Factor both denominators..
4(y+2) and y(y+2)
So the common denominator would be 4y(y+2)
The first fraction is missing a "y" so multiply the numerator by y to get y^2
The second fraction is missing a "4" so multiply the numerator by 4 to get 4
(y^2 - 4)/(4y(y+2))
So can factor the numerator to get (y+2)(y-2). There if a (y+2) on top and bottom so they cancel out.
Answer: (y-2)/4y
Answer:
A, D,E
Step-by-step explanation:
They are all divisible by 5
Answer:
25
Step-by-step explanation:
10 times 5 equals 50
50 divided by 2 equals 25
