Answer:
C. 
Step-by-step explanation:
The formula for surface area is
LA + 2B
LA indicated Lateral Area and can be found multiplying perimeter of base by the height.
7 + 7 + 14 + 14 = 42 * 7 = 294
Multiply the LA from above with the area of base times 2.
98 * 2 = 196
294 + 196 = 490, so the surface area of the rectangular prism is 490 units.
What expression where are they
Answer:
When Sum of square of two Sides is equal to square of third side of triangle.
Step-by-step explanation:
Given:
Three side length of triangle are given we need find the which value to substitute for a, b, c in Pythagoras theorem.
First we will find the squares of all length, then we will check which two square of side are equal to square of third side as per Pythagoras theorem.
Hence the two side would according be a and b and third side will become c.
For example if length of triangle is given as 6 cm, 8 cm and 10 cm.
We will first take square of all

Now we can see that

Now by Pythagoras theorem.

Hence we can say a = 6 cm, b = 8 cm, c= 10 cm

Which of the following is equivalent to 6.32 x 10-*3?
In order to find the answer to this question you can just put the notation into standard form which means they will be equivalent to each other.
The exponent is negative so you move to the left:

=
Therefore 6.32*10^-3 is equivalent too (c) .00632
