Answer:
36
Step-by-step explanation:
Triangle FED and Triangle AEC are similar.
That means, the ratio of corresponding sides are equal. Thus we can say:
Also, since EC is 39 and D is the midpoint, ED and DC are half of that. Hence ED = 39/2 = 19.5
Now we can use the ratio to solve for AC:
Hence, AC = 36
Answer:
3 - 48
Step-by-step explanation:
Given
(a + 2)(3a² + 12)(a - 2)
= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL
=(a² - 4)(3a² + 12) ← expand using FOIL
= 3 + 12a² - 12a² - 48 ← collect like terms
= 3 - 48
a) the Probability p( red, red, red) is 0.83%.
b) the probability p(white, red, white) is 0.
<u>Step-by-step explanation:</u>
The total number of marbles = 3+6+1.
=10.
a) to find the Probability p( red, red, red).
p( red, red, red)=
p( red, red, red)=×
×
.
p(red,red,red)= 0.0083.
p(red,red,red)=0.83%
b)to find the probability p(white, red, white).
p(white, red, white) is 0.
Since there is only one white.
