Answer:
10
Step-by-step explanation:
12/20 = 6/x
Using cross products
12*x = 20*6
12x = 120
Divide by 12
12x/12 = 120/12
x = 10
The graph intersects the x-axis at 2 points, therefore there are 2 values of x for which y = 0, meaning there are 2 solutions.
Answer:
Quadruple the size
Step-by-step explanation:
Explanation:
When you enlarge a linear measurement by a scale factor a the area changes by a scale factor a2
So when you double the radius. scale factor 2, the area is increased by a scale factor:
22=4
So the area is quadrupled in this case.
450 can be divided by 2 and 5. 229 can not be divided by any. 228 can be divided by 2 but not 5.
The correct answer is 3x+90=180
<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>
<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>
