Step-by-step explanation:
next time you answer someone's question with a bunch of random letters just to get the points don't. It rude especially sense you have questions you want answered. Now I could be nice and help you because I know how to solve this and you obviously don't, but I'm giving you the same curtesy as you did me and writing a bunch of gibberish.
If h + 12 = 22, then h = 10.
This uses the subtraction property of equality, because if 12 is subtracted from both sides, we get the result of h = 10.
Hey!
First, we need to know how many millimeters are in a centimeter.
<em>10 mm = 1 cm</em>
Okay, now we can write an equation.
<em>360 mm ÷ 10</em>
To solve this equation, we simply divide.
<em>360 mm ÷ 10 = 36 cm</em>
<em>So, if </em><span><em>Anoki bought 360 millimeters of fabric, that means he has </em> 36.0 centimeters <em>of fabric.</em>
Hope this helps!

The intersection point is only one. Then the equation of the line is tangent to the circle at point (1, -2).
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
Prove algebraically that the straight line with equation x = 2y + 5 is a tangent to the circle with equation x² + y² = 5.
x = 2y + 5 ...1
x² + y² = 5 ...2
If the intersection of the point of the circle and line is one. Then the line is tangent to the circle.
Then from equations 1 and 2, we have
(2y + 5)² + y² = 5
4y² + 25 + 20y + y² - 5 = 0
5y² + 20y + 20 = 0
5y² + 10y + 10y + 20 = 0
5y (y + 2) + 10(y + 2) = 0
(5y + 10)(y + 2) = 0
y = -2, -2
Then the value of y is unique then the value of x will be unique.
The value of x will be
x = 2(-2) + 5
x = -4 + 5
x = 1
The intersection point is only one. Then the equation of the line is tangent to the circle at point (1, -2).
