To factor completely the expression, factor out first the numerical coefficients, 8 and 36. The factors of 8 are 2 x 2 x 2 while that of 36 is 2 x 2 x 9. The complete factorization of the given expression above will give us the answer of,
(2)(2)(2y - 9)
Answer
36 + 4x.

She walked 1/10 of a mile in one minute
work: 1/2 a mile is 0.5 and 0.5 divided by 5 is 0.1 so you get 0.1 mile for each minute
Answer:
£3.50
Step-by-step explanation:
£4.90 = 7/8
£4.90/(7/8) = £5.60 (Total Amount of Money)
£5.60 x (5/8) = £3.50
Answer:
hole at x=-3
Step-by-step explanation:
The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)
The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.
So anyways we have (x+3)/(x^2-9)
= (x+3)/((x-3)(x+3))
Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.
