Answer:
Since both terms are perfect squares, factor using the difference of squares formula,
a
^2
−
b
^2
=
(
a
+
b
)
(
a
−
b
)
where
a
=
y
and
b
=
6
(
y
+
6
)
(

)
Answer:
a
Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint
b
The number is ![x= \frac{1}{3}](https://tex.z-dn.net/?f=x%3D%20%20%5Cfrac%7B1%7D%7B3%7D)
c
The price is ![P = \$ 8](https://tex.z-dn.net/?f=P%20%20%3D%20%5C%24%208%20)
Step-by-step explanation:
From the question we are told that
The ratio of the number of cups of blue paint to the number of cups of red paint is ![r = 3: 1](https://tex.z-dn.net/?f=r%20%20%3D%20%203%3A%201)
Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint
Given that 1 cup of red paint => 3 cups of blue paint
x cup of red paint => 1 cup of blue paint
So
![x= \frac{1 * 1}{3}](https://tex.z-dn.net/?f=x%3D%20%20%5Cfrac%7B1%20%2A%20%201%7D%7B3%7D)
=> ![x= \frac{1}{3}](https://tex.z-dn.net/?f=x%3D%20%20%5Cfrac%7B1%7D%7B3%7D)
Generally the unit price of a cup of blue paint is mathematically represented as
![P = \frac{48}{6}](https://tex.z-dn.net/?f=P%20%20%3D%20%20%5Cfrac%7B48%7D%7B6%7D)
=> ![P = \$ 8](https://tex.z-dn.net/?f=P%20%20%3D%20%5C%24%208%20)
Answer:
19 6j/5
Step-by-step explanation:
52m^2= 2[(x-5)+(x)]. 52m^2= 2(2x-5). 52m^2=4x-10
