Ratio of the radii = sqrt16 / sqrt81 = 4/9
so radius of circle Q is found by solving 4/9 = 8/x where x = radius of Q
x = 2*9 = 18
radius of circle Q = 18.
Answer:
(x + 4)(x - 4)
Step-by-step explanation:
There are actually quite a lot of pairs of binomials the disproves Eric's conclusion, but they all model after the same special product: a^2 - b^2.
The special product a^2 - b^2 can be factored into (a + b)(a - b) and for all real a and b, it will come out as a binomial.
Here is an example:
(x + 4)(x - 4)
We can use the distributive property to get:
x^2 - 4x + 4x - 16
which is the same as
x^2 - 16
This would disprove Eric's conclusion.
Answer:
d. 4.5
Step-by-step explanation:
10x-5=16x+22
-22 -22
10x-27=16x
-10x -10x
-27=6x
x=4.5
Answer:
4) 3 for the numerator. 9 for the denominator
5) 6 for the first blank square and 48 for the second blank.
6) 2 for the denominator. 6 for the numerator. 30 for the second numerator.
