Answer:
792 m^2
Step-by-step explanation:
We can split the shape up into two different shapes. The first shape is the bigger rectangle, with an area of 18 x 30. The second shape will have an area of 6 x (60-18). This is because we have to subtract the length of the large rectangle's side. The two areas are 540 and 252. When we add them together, we get 792. Since this is the area, it will be squared, leaving us with 792 m^2.
Hope this helps :)
That could be expressed in two different ways ... because
there are no parentheses in your question.
One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .
The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .
Y is equal to 4-3x/4 and X=16/3 -4y/3
Answer:
C. 70
Step-by-step explanation:
In the expansion of (a + b)^n, the k-th term is ...
nCk·a^(n-k)b^k . . . . . k = 0 to n; nCk = n!/(k!(n-k)!)
Here, we have n=8, k=4, so the term of interest is ...
8C4·x^4y^4 = (8·7·6·5)/(4·3·2·1)x^4y^4 = 70x^4y^4
The coefficient of the term is 70.
Answer:
Equation 1 = Equation 2
165 - 4x = 145 - 3.50x
Step-by-step explanation:
Let x represent the number of 30-day periods.
Tavon has a gift card for $165 that loses $4 for each 30-day period it is not used.
Therefore the equation =
$165 -$4 × x
= 165 - 4x.......... Equation 1
He has another gift card for $145 that loses $3.50 for each 30-day period it is not used.
$145 -$3.50 × x
= 145 - 3.50x........... Equation 2
Hence, an equation for the number of 30-day periods until the value of the gift cards will be equal is obtained by equating Equation 1 and Equation 2 together
So, we have
Equation 1 = Equation 2
165 - 4x = 145 - 3.50x
We simplify further:
165 - 145 = -3.50 + 4.0x
20 = 0.5x
x = 20/0.5
x = 40
Therefore, number of each 30-day periods until the value of the gift cards will be equal is 40
