Step-by-step explanation:

Surface Area of Figure = Area of 4 triangular sides + Area of Base

$4 \times ( \frac{1}{2} \times base \times height) + (length \: \times \: width) \\ = 4 \times ( \frac{1}{2} \times 10 \times 12.1) + (10 \times 10) \\ = 4 \times 60.5 + 100 \\ = 242 + 100 \\ = 342 {yd}^{2}$

Answer: For no solution it would mean that there is no answer to the equation. For infinite solutions it would mean that any value for the variable would make the equation true.

Explanation: For example of no solution 6=5 as you can tell 6 is not the same to 5 so there is no solution. More examples are 2=3, 8=10, and 1=0. For infinite solutions examples are 2=2, 7=7, and 10=10 as we can see 2 does equal 2 and 7 equals 7 which makes it true and infinite.

Answer:

$\Huge \boxed{2210}$

Step-by-step explanation:

PEMDAS

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract the numbers from left to right. Please Excuse My Dear Aunt Sally!

First, parenthesis.

$\displaystyle 50+80=130$

Answer:

The coordinates of the vertices of triangle A'B'C' are $A'(x,y) = (0,-4)$ , $B'(x,y) = (2,-1)$ and $C'(x,y) = (3,-5)$ .

Step-by-step explanation:

According to this statement, triangle ABC must be translated 5 units in the -y direction to form triangle A'B'C'. We need to use the following operations:

$A'(x,y) = A(x,y) +(0,-5)$ (1)
