Answer:
2 the scale factor is 4
3 a (6,6) b (12,18) c (18,6)
4 a (1,1) b(2,3) c (3,1)
5 the scale factor is 2
Step-by-step explanation:
have a good day :)
4x² - 100 = 0
<u> + 100 + 100</u>
<u> 4x²</u> = <u>100</u>
4 4
x² = 25
x = <u>+</u>5
4(5)² - 100 = 0
4(25) - 100 = 0
100 - 100 = 0
0 = 0
4(-5)² - 100 = 0
4(25) - 100 = 0
100 - 100 = 0
0 = 0
The roots of the equation is positive or negative 5.
Answer:
57.97507788%
Step-by-step explanation:
Write the problem as a mathematical expression.
<u>372.2</u>
642
Multiply by 100 to convert to a percentage.
<u>372.2</u>
642 * 100
Simplify
<u>372.2.</u>
642. * 100 = 57.97507788%
