Angle UTV is basically given: it's 138°.
Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have
So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°
1/7-9/7n+6/7
1-9/7n
That is the extended form and is simplified
Hope it helps! :)
In completing the square, the first step is to factor out the first and second term so that the factor (x+a) is highlighted. This is seen in line 1. However, in line 2, the subtracted value should be 3 so as to compensate for the added value. This affects then line 3 as well. The answer is line 2.
Answer:
<em>(2x-y+2)(2x+y-2)</em>
Step-by-step explanation:
4x² - y² + 4y - 4=
=(2x)²-(y²-4y+4)
=(2x)²-(y-2)²
= [2x-(y-2)][2x+(y-2)]
<em>=(2x-y+2)(2x+y-2)</em>
a²-b²=(a-b)(a+b)
