- A square handkerchief has a side of 2x + 3.
- So, it is given that the handkerchief is a square.
- So, in other words we have to find out the area of a square.
- We know, area of a square = side²
- Therefore, the area of the handkerchief
- = (2x + 3)²
- = (2x)² + 2(2x)(3) + (3)²
- = 4x² + 12x + 9
<u>Answer</u><u>:</u>
<u>The </u><u>area </u><u>of </u><u>the </u><u>square </u><u>handkerchief</u><u> </u><u>is </u><u>4x² + 12x + 9</u><u>.</u>

Answer:
Slope/gradient = Rise/run
Rise = -2
Run= 1
Slope=-2
Answer:
Option B
Option C
Step-by-step explanation:
we need to divide the coefficient of x by half since it is required for completing square, this term is added and subtracted at the same time to keep the equation intact, so we have
later we have
we know
we have
or
so we have
finally
The second is obtained by summing the two given equations
f(x)=8x-10
g(x)=3x+5
-----------------
f(x)+g(x)=11x-5
Step-by-step explanation:
The quadratic formula is:
A, in this case, is -2.
B is 5
C is -11
x =
x =
x =
x = and
We can break up the fraction to make it easier on our eyes
x =
≈1.9843
x =
bearing in mind that a whole is simply same/same or just 1.
3 dozen, there are 3 dozens in 3 dozen, obviously
dozen dozen dozen.
in 2 dozens, there are 2 of course
dozen dozen.
if 3 dozens is three thirds namely 3/3 = 1 = whole, then 2 dozens is just two of those dozens, namely two thirds, 2/3.
so if we use that many ingredients to make a whole three thirds, how much will it be to make only two thirds of it? well, is simply their product, so we'll simply multiply each ingredient amount by 2/3.
