Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
The gcm is 30 and the lcm is 5
Answer:
x = imaginary number
x₁ = 2<em>i</em>
x₂ = 6<em>i</em>
Step-by-step explanation:
x/(x - 5) =4/(x - 4)
x(x-4) = 4(x-5)
x*x + x*-4 = 4*x * 4*-5
x² -4x = 4x - 20
x² -4x - 4x + 20 = 0
x² - 8x + 20 = 0
x = {-(-8)±√((-8²)-(4*1*20))} / (2*1)
x = {8±√(64-80)} / 2
x = {8±√-16} / 2
√(-16) ∈<em> i</em>
<em>i </em>= set of imaginary numbers
√-16 = -4<em>i</em>
then:
x = {8±(-4<em>i</em>) } / 2
x₁ = {8+(-4i)}/2 = {8-4i)/2 = 4i/2 = 2i
x₂ = {8-(-4)}/2 = {8+4i}/2 = 12i/2 = 6i
Hehe hehe hehe hehe hehe hehe hehe hehe hehe heh Greg Greg heh the answer is D
