The first number is 20
The second is 40
The third is 70
the first number = a
The second number = 2a
The third number = 3 1/2a
6 1/2a = 130
a = 20
Hope this helps!
Let
x--------> <span>represents the length of a single tile
L-------> t</span><span>he length of the floor
W------> the</span><span> width of the floor
A--------> </span>area of a tiled kitchen floor
<span>
we know that
A=W*L
A=</span>4x²<span> + 24x + 27
</span>so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2
substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]
therefore
the answer is
the <span>expression that represents the width of the kitchen in terms of x is
</span>W=[4x² + 24x + 27]/[2x+9]
Answer:
See below
Step-by-step explanation:
Expand it a bit to see:
= ![\sqrt[5]{ 2^5 * 7 * x^5 * x^5 * x * y^5 * y^3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%202%5E5%20%2A%207%20%2A%20x%5E5%20%2A%20x%5E5%20%2A%20x%20%2A%20y%5E5%20%2A%20y%5E3%7D)
=![2x^2y \sqrt[5]{7xy^3}](https://tex.z-dn.net/?f=2x%5E2y%20%5Csqrt%5B5%5D%7B7xy%5E3%7D)

Answer:
Option a) 62.2 square feet
Step-by-step explanation:
we know that
The dilation is a non-rigid transformation that produces similar figures
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the large shape
y ----> the area of the small shape
so
we have
substitute
solve for x
