Find the area and perimeter of a rectangle that has a length of (x + 24) and (x + 16). Show all work for full credit.

klio [65]

Answer:

Perimeter of rectangle = 4x + 80

Area = x² + 40x + 384

Step-by-step explanation:

Perimeter of rectangle = 2*(length + width)

= 2* (x + 24 + x + 16)

= 2*( x +x + 24 + 16) {Combine like terms}

= 2* (2x + 40)

Use Distributive property : a*(b +c) = a *b + a*c

= 2*2x + 2*40

= 4x + 80

Area of rectangle = length * width

= (x + 24) (x + 16) {use FOIL method}

= x*x + x*16 + 24*x + 24*16

= x² + 16x + 24x + 384 {Combine like terms}

= x² + 40x + 384

Ellen saved $2000 and she spent 10% of it to buy a bike. Kim saved 8% more than that of Ellen's left savings. If Lisa saved 60%

enyata [817]

Answer: Lis saved $1166.4 .

Step-by-step explanation:

Given , Ellen saved $2000 and she spent 10% of it to buy a bike.

Then, Ellen's left saving = saved amount - 10% of (saved amount)

= $2000 - 0.10 x $2000 [We convert perecntage to decimal by diving it by 100]

= $2000 - $200

= $1800

So, Ellen's left saving= $1800

Also, Kim saved 8% more than that of Ellen's left savings.

Kim's Saving = Ellen's left saving + 8% of (Ellen's left saving)

= $1800 + (0.08) x ($1800) [We convert perecntage to decimal by diving it by 100]

= $1800 + $144

i.e. Kim's Saving= $1944

If Lisa saved 60% as much as Kim, then Lisa's saving = 60% of (Kim's Saving)

= (0.60) x ($1944) [We convert perecntage to decimal by diving it by 100]

i.e. Lisa's saving = $1166.4

Math graph equation. (Picture.)

vladimir1956 [14]

Answer:

y = -2x + 3 is the required equation

Step-by-step explanation:

From the graph we will get two ordered pairs

If we see that When x=0 then y=3 and when x = 1 then y=1

Now from this we can find the slope of the Graph

So slope of graph = (y2 - y1) / (x2-x1)

=(1-3) / (1-0)

=-2

So

Slope = m = -2

Now the equation is

y = mx + b

We have to find the value of b

as we have two ordered pairs we can take any of it to find the value of b because line passes through those points

taking (0,3) as a point

y= mx + b

put values

3 = -2*(0) + b

so

b=3

Now the equation of the line in this form is

y = mx + b

which is

y = -2x + 3

Which of the following investments could be represented by the function A = 250(1 + 0.08/12)12 × 4?

Alekssandra [29.7K]

hello,

the first term is 250 so this is the initial invested amount

$(1+\dfrac{0.08}{12})^{12}=(1+\dfrac{8\%}{12})^{12}$

is to compute 8% annual interest compounded monthly (there are 12 months in a year)

and then multiply by 4 means that it is computed for 4 years so

finally the answer is

$250 is invested at 8% annual interest compounded monthly for 4 years

hope this helps
