The solution is:
small square side = 9 inches
large square side = 9 + 3 = 12 inches.
Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object. Area of a square (A) is the product of its length (l) and width (l).
i.e. A= l× l
Let the smaller square have a side length of s
The the larger square have a side length of s + 3
Total area of the two squares is 225
Formula
s^2 + (s + 3)^2 = 225
Expand
we get,
Solution
s^2 + s^2 + 6s + 9 = 225
2s^2 + 6s + 9 = 225
Subtract 225 from both sides
2s^2 + 6s - 216 = 0
This factors.
( x - 9)(x + 12) = 0
x - 9 =0
x + 12 = 0
x = 9 is the only valid root for this question.
Hence, The solution is:
small square side = 9 inches
large square side = 9 + 3 = 12 inches.

Answer:
Option B and C are correct.
Step-by-step explanation:
Find the expanded form of 840.02.
Any decimal number can be expanded in the form of power of 10.
then;
In 840.02
the first 8 is
8 hundreds i.e, 800 ,
4 is 4 tens i.,e 40 ,
0 ones ,
0 one-tenths and
2 hundredths,
we can write this as;
or
or
Answer:
8 × 100 + 4 × 10 + 2 × 1/100
8 × 100 + 4 × 10 + 0 × 1 + 0 × 1/10 + 2 × 1/100
Step-by-step explanation:
8 × 100 + 4 × 10 + 2 × 1/10 =800+40+2/10 = 840+2/10 = 840.2
8 × 100 + 4 × 10 + 2 × 1/100 = 800+40+2/100 = 840+2/100 = 840.02
8 × 100 + 4 × 10 + 0 × 1 + 0 × 1/10 + 2 × 1/100 =800+40+2/100= 840.02
8 × 100 + 4 × 10 + 4 × 0 + 0 × 11 + 2 × 1/10=800+40+2/10= 840+2/10 = 840.2
Answer:
The expression that represents the price as a function of months is "gas(x) = 1.99*(1.06)^x" and after 14 months the price will be "gas(14) = 4.4992"
Step-by-step explanation:
Since it grows at a rate of 6% every month, then it starts as:
gas(0) = 1.99
On the first month:
gas(1) = gas(0)*(1.06)
On the second month:
gas(2) = gas(1)*1.06 = gas(0)*(1.06)*1.06 = gas(0)*(1.06)²
And so on. So the price growth can be modelled by the following expression:
gas(x) = gas(0)*(1.06)^x
Where x is the number of the month.
After 14 months the price will be:
gas(14) = 1.99*(1.06)^14 = 4.4992
