Answer:
204 ft^2
Step-by-step explanation:
<u>triangle on the left</u>:
A= l x w x 1/2
A = 12 x 5 x 1/2
A = 30 ft^2
<u>triangle on the right</u>:
Same thing
A = 30 ft^2
<u>square in the middle</u>:
A = l x w
A = 12 x 12
A = 144 ft^2
<u>Add them up</u>:
30 + 30 + 144 = 204 ft^2
Answer:
15x+10-8x+2
7x+12
Step-by-step explanation:
By identifying the largest exponent in each expression, we see that the answers are:
a) D = 3.
b) D = 5.
c) D = 0.

How to determine the degree of an expression?</h3>
The degree is just the largest exponent of the variable in an expression.
First, we have:
a) √3xyz - 5
The largest exponent is on the term √3*xyz is 3 (because we add the 3 exponents 1 of x, y, and z) so this expression has a degree of 3.
b) y² - 3y⁵ -y + 2y³ - 4
Here the largest exponent is on the second term, so we can see that the degree is 5.
c) -10³
Here we don't have a variable, so this is a constant, which means that the degree is zero, because we could write:
-10³*x⁰
Where we use the fact that x⁰ = 1

Answer:
42 blocks
Step-by-step explanation:
If each block is 2 inches, and the height of the door is 84 inches, you need to divide the height by the block size. Once you divide 84 by 2, you should get 42 blocks as your answer.
