I believe what you're looking for is the expanded form, which would be x^2+10x. It does look like you're missing a part to the second () however.
8,000,000 would be the answer to 4000x2000. Hope this helps!
There are 15 marbles in the bag. This gives us the probability of picking a red marble as 5/15, or 1/3. Because you replace the marble therefore making the probability the same each time, and as it's a logical 'and' operation, you multiply the probabilities like this:
(1/3)•(1/3)=(1/3)^2
Because (a/b)^c = a^c/b^c, P(two red marbles) = 1^2/3^2 = 1/9.
We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.
The formula of an area of a triangle:
Triangle #1:
b = 9ft and h = 12.3ft. Substitute:
Triangle #2:
b = 11ft and h = 11.9ft. Substitute:
The Lateral Area:
<h3>Answer: B. 241.6 ft².</h3>
