Step-by-step explanation:
This quadratic is of the form
where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).
The value of x in all case is
1. The value of x is 2
2. The value of x is 1
3.The value of x is 57
4.The value of x is 93
<h3>What is complementary and supplementary angle?</h3>
If the sum of two angles is 180 degrees then they are said to be b angles, which form a linear angle together. Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.
1. As the given angle is 90 degree i.e., complementary angle.
So,
54+10x+16=90
20=10x
x=2
2. 65x-12=43x+10 (Vertically opposite angle)
22x= 22
x=1
3. 72= x+15 (Vertically opposite angle)
x= 57
4.x+244+23=360 (Complete angle)
x=93

A if 8 and 12 are legs the missing side would be 14.42
B if 8 is a leg and 12 is hypotenuse then the other leg would be 8.94
Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.
You said that <u>3t - 7 = 5t
</u>OK. Fine.
Let's just find out what <em>6t</em> is.
Subtract 3t from each side: -7 = 2t
Multiply each side by 3 : <em>-21 = 6t
