Answer:
120 ft. sq
Step-by-step explanation:
You use the equation length times width to find the area. 15 x 8 = 120. This equation works for any rectangle
Answer:
A, C, E
Step-by-step explanation:
By analyzing the graph, we can see that the roots are 
and 
.
We now want to find all equations of the form 
.
This immediately gives C as 1 answer.
We can expand our equation to find other possible solutions!
By the FOIL method: 
We can then divide both sides of the equation to find that 
, so A is another answer.
We can complete the square on 
to find the last possible solution.
.
We can then multiply both sides of the equation by 
to find that 
, so E is the last answer.
The proof that the other answers don't work is left as an exercise.
So, the answers are A, C, and E, and we're done!
Answer: The volume is the product of the Length, Width, and Height: V = LWH.
Step-by-step explanation: We are given V = 240 in.3, and H = 6 in., and L = W + 3 in.
Thus 240 in.3 = (W+3 in.)*W*(6 in.) so W(W+3 in.) = 240 in.3 / 6 in. = 40 in.2
Using the distributive property and moving the constant to the left gives:
W2 + (3 in.)W - 40 in.2 = 0
This factors:
(W + 8 in.)(W - 5 in.) = 0
The first factor gives W = -8 in. which is nonsense because it is negative.
The second factor gives a valid answer of W = 5 in.
Answer:
35
Step-by-step explanation:
Law of cosines
c^2=a^2+b^2-2ab(cos(A))
14^2=11^2+8^2-2(11)(8)Cos(A)
A=93.5833
Law of Sines
Sin(A)/a=Sin(B)/a
Sin(93.5833)/11=Sin(B)/8
B=34.7719
Answer:
8 weeks
Step-by-step explanation:
$2100 - $900 = $1200
$1200/$150 = 8 weeks
