find the ratio between the two triangles:

40 on the left corresponds to 50 on the right = 40/50 = .8

.8 is the fixed ratio between these two triangles.

to find x:

43 x .8 = 34.4

x = 34.4

"angles of similar triangles are always congruent."

a: 63

b: 88

c: 29

What is the gcf of 21 30 anwhat is the gcf of 21 , 30 ,and 44?
Ymorist [56]
Find the prime factorization of each value.

21 is 7*3

30 is 3*10 which can be further broken down into 3*2*5

44 is 4*11 which can be further broken down into 2*2*11

What do they share in common?
21 and 30 each have a 3 in common.
Therefore the GCF(21, 30) = 3.

21 and 44 share a 2 in common.
But if we're looking at all three of them together, they share nothing in common.

The equation 2x^2+12x=4 is written in the form of 2(x-p)^2+q=0. what is the value of q?
hram777 [196]

1) Factor out the coefficient 2:  2x^2+12x=4 => 2(x^2 + 6x) = 4

2) Complete the square of x^2 + 6x:  x^2 + 6x + 9 - 9.  Then:

                                                    2(x^2 + 6x + 9 - 9) = 4

3) Rewrite the square as the square of a binomial:

                                                    2( [x+3]^2 - 9) = 4, or

                                                     2([x+3]^2)       = 22, or

                                                     2( [x+3]^2 ) - 22 = 0

The value of q is -22.
