To factor an expression, you need to find the GCF or Greatest Common Factor of all of the pieces of the expression.
The greatest common factor of 5x and -10 is 5. So, when we factor this, we divide both pieces of the expression by 5.
Your final answer is 5(x-2)

Answer:
Step-by-step explanation:
Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:
and cross multiply to get
21x = 126 and
x = 6
Answer:
-4×-2y=2
-4×+8y=-8
6y=6
y=1 then you the value of y and to put in any one equestion
Answer:
4x + 1
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x) , thus
f(x) + g(x)
= x + 3x + 1 ← collect like terms
= 4x + 1
