Considering the area of the rectangle, we have that the length is of 8 units and the width is of 10 units.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given as follows:
A = lw.
In this problem, the area is of 80 square units, while the length and the width are consecutive even integers, hence:
Then:
l(l + 2) = 80
l² + 2l - 80 = 0
(l + 10)(l - 8) = 0.
We need the positive measure, hence:
l - 8= 0 -> l = 8 units.
w = l + 2 = 10 units.

Answer:
14π cm
Step-by-step explanation:
Circumference of a circle given the diameter is :
πd
We simply substitute the value given in the image into our formula to find our answer:
πd = π×14 = 14π
Units will be cm as circumference is a length
This is our final answer as the question states to leave it in pi form .

Step-by-step explanation:
let the total charge be y
and the number of rose be x
Florist A charges
y=40+4.75x---------1
Florist B charges
y=25+5.2x--------2
to solve for the number of roses we need to equate 1 and 2
40+4.75x=25+5.2x
40-25=5.2x-4.75x
15=0.45x
x=15/0.45
x=33.33
The number of roses that will be less expensive to order from A is 33.33
Do #1- 32x4= 128, #2- 128x4= 512, do you also need to know the fractions? (I think)
5(2x+5y=16)+2(-5x-2y=2)
10x-10x+25y-4y=80+4
21y=84
y=4, making 2x+5y=16 become:
2x+5(4)=16
2x+20=16
2x=-4
x=-2
So the solution to the system of equations is the point (-2, 4)
