Answer:
$ 2330
Step-by-step explanation:
a = $240
Earning at the end of fifth week = $ 680
increase in earnings per weak = ( 680 -240)/2 = 440/2 =110
d =110
l = a + (n-1)d
a20 = 240 + (19 * 110 ) = 240 + 2090 = 2330

Given
(- 12x + 4) +
(6x + 8) ← distribute parenthesis

The first four.
Step-by-step explanation:
There are 3 main postulates. SSS, SAS, and AAS. This simply refers to how we prove a triangle congruent. With SSS, all 3 sides must be congruent (either proven or given).

This is when you have a set of angles congruent with sides on each side congruent as well (look at the first four as an example of this.

All rhombuses have 2 pairs of parallel sides.
The answer is, x-5 equals to 0. So x equals to 5. So your answer is 5.
