Answer:
they aren't the same ratio
Step-by-step explanation:
ratio of 5:10 then 9:15
5/10 and 9/15
and that is simplified
2.5/5 and 3/5 so they aren't the same ratio
You cannot simplify the fraction 4/21, because you would have to divide 21 by 4, which would end in a decimal answer, therefore you cannot simplify it.
Answer:
x=-30
Step-by-step explanation:
x+34=4
-34 -34
x=-30
Answer:
1. x = 30
2. x = 39
Step-by-step explanation:
1.
4x and ( 3x + 30 ) are alternate exterior angles,
Alternate exterior angles are equal.
4x = 3x + 30
4x - 3x = 30
x = 30
2.
x and ( 3x + 24 ) are co - interior angles.
Sum of co - interior angles is 180,
x + 3x + 24 = 180
4x + 24 = 180
4x = 180 - 24
4x = 156
x = 156 / 4
x = 39
Answer:
Step-by-step explanation:
If the zero occur when x={5, -2, -1} then the equation must be
(x-5)(x+2)(x+1) if expansion is desired
(x^2-3x-10)(x+1)
x^3+x^2-3x^2-3x-10x-10
x^3-2x^2-13x-10
