Answer:
12/7
Step-by-step explanation:
5/3x+10/7=30/7
5/3x=30/7-10/7
5/3x=20/7
x=(20/7)/(5/3)
x=(20/7)(3/5)
x=60/35
simplify
x=12/7
Answer:
B) 
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:
The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:
Finally, we sum both of the areas found to calculate the total area.
So, the answer is option B).
Hey there!
When multiplying variables with the same degree, be sure to add the two degrees being multiplied.
For example;
x * x; both of these terms have the degree of "1" as they are "x^1". Since we are multiplying them, we need to add their degrees.
x^1 * x^1 = x^2
Now that we've broken down what we are doing, let's apply this new knowledge to your problem.
(x^3)(x^-2); Remember to just add the degrees; -2 + 3 = 1
This means our product is x^1, or just x.
I hope this helps!
