Step-by-step explanation:
Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar.
Answer:
1. 12x+7
2. x=7
Step-by-step explanation:
1. 4(5x-1)-8x+11=?
multiply 4(5x-1)
20x-4-8x+11
Subtract 8x from 20x which is 12x
then subtract 4 from 11 which is 7
12x+7
Answer:
translation up
Step-by-step explanation:
(In the picture, QRST looks like a rhombus, so I will assume that it is a rhombus.)
In a rhombus, opposite angles are congruent based on the alternate interior angle theorem. In other words, R and T along with Q and S are both alternate interior angle pairs.
(You can actually test this by printing out a rhombus, cutting out the angles, and matching up the opposite ones.)
We know that Q is equal to 4x + 10, but we need to solve for x. Since Q and S are congruent, we can set them equal to each other:
1) 4x + 10 = 5x - 3
2) 4x + 13 = 5x
3) 5x = 4x + 13
4) x = 13
Now let's plug 13 in for Q:
5) 4(13) + 10 = 52+10 = 62
I got m<Q = 62 degrees. Hope this helps!
To factorize a polynomial you need to find the zeros, and then you can write the polynomial as a product of bynomials.

How to factor a polynomial?</h3>
For a polynomial of the form:
We define the zeros as the values of x such that:
p(x) = 0.
On the above case, the degree of the polynomial is n (the maximum exponent). Then the number of zeros of the polynomial is n (same as the degree).
Once we know the n zeros, we can factorize the polynomial as:
For example, for the polynomial:
The two zeros are x = 2 and x = -2, then it can be rewriten as:
