Answer:
<h2>x = 6.5 cm</h2>
Step-by-step explanation:
The segment 20.2 cm is the tangent. Therefore x and 20.2cm are perpendicular.
Use the Pythagorean theorem:

We have

Substitute:
<em>use (a + b)² = a² + 2ab + b²</em>
<em>subtract x² from both sides</em>
<em>subtract 216.09 from both sides</em>
<em>divide both sides by 29.4</em>

Answer:

Step-by-step explanation:
In the distributive property each value inside the parenthesis will be multiplied by the value outside the parenthesis.
In the expression 3(x - 1) it will look like:

Then we multiply both value separately giving us:

So in conclusion it would be right to assume that.

.
Answer:
Step-by-step explanation:
y = mx + b
slope(m) = 1/9
y int (b) = 8.....or (0,8)
y = 1/9x + 8.....this is ur equation
ur x intercept is : (can be found by subbing in 0 for y
0 = 1/9x + 8
-1/9x = 8
x = 8 * -9
x = - 72....or (-72,0)
