Answer:
Area = 960 cm^2
Step-by-step explanation:
Perimeter (P) = 2 (l + w)
P = 2l + 2w
Let the length be 5x
Let the width be 3x
From the question, P = 128.
Therefore:
128 = 2l + 2w
Divide both sides by 2.
l + w = 64
Recall we said:
l = 5x
w = 3x
So then:
5x + 3x = 64
8x = 64
Divide both sides by 8
x = 64/8
x = 8.
Since x = 8
Length = 5x = 5*8 = 40cm
Width =3x = 3 * 8 = 24cm
Area of a RECTANGLE:
Area = length * width
Area = 40 * 24
Area = 960 cm^2
Answer: 250
40% of 350 is 140
350 minus 140 is 210
210 plus 40 = 250
Answer:
$55.
Step-by-step explanation:
We have been given that a website-hosting service charges businesses a onetime setup fee of $350 plus d dollars for each month. A business owner paid $1,010 for the first 12 months, including the setup fee.
We can use our given information to form an equation as: 
Now let us solve for d.
Therefore, the value of d is $55.
Answer:
B
Step-by-step explanation:
Since the y coordinate of the vertex is -4, it has to be the rest of the equation subtracted by 4, which eliminates A and C.
Adding 5 puts it on the left side, so you have to subtract 5.
Then you add all the default info and the info we found out.
y = 2(x-5)^2-4
So technically by process of elimination, B must be the answer.
