Answer:
Step-by-step explanation:
One is given the following expression:
In order to simplify and solve this problem, one must keep the following points in mind: the square root function (
) is a way of requesting one to find what number times itself equals the number underneath the radical sign. One must also remember the function of taking the square root of a negative number. Remember the following property: (
). Simplify the given equation. Factor each of the terms and rewrite the equation. Use the square root property to simplify the radicals and perform operations between them.
Take factors from out of under the radical:
Simplify,
For this case we must factor the following expression:
We rewrite the middle term as a sum of two terms whose product is
And whose sum is
These numbers are:
-5 and -3
So:
We factor the maximum common denominator of each group:
We take common factor
Answer:
1/5 is equal to 2/10 so the one with 3/10 has more
9514 1404 393
Answer:
B. 32 square inches
Step-by-step explanation:
Each of the two triangular faces has an area of ...
A = (1/2)bh = (1//2)(6 in)(4 in) = 12 in²
The lateral surface area is the product of the prism height (0.5 in) and the perimeter of the base.
LA = (0.5 in)(5 in +5 in + 6 in) = 8 in²
So, the total area is the area of the two base and the lateral area:
SA = 2A +LA
SA = 2(12 in²) +8 in² = 32 in²
The surface area of the prism is 32 square inches.
