Hi... So for this homework question It says " Amy bought 2 and 1/2 gallons of paint for $60. What is the cost for 1 gallon of pa
andrey2020 [161]

I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

2+\dfrac{1}{2} = \dfrac{4}{2}+\dfrac{1}{2}=\dfrac{5}{2}

So, we know that 5/2 gallons cost 60 dollars, which means

\dfrac{5}{2}g=60

To find the cost of a single gallon, we have to solve the equation for g:

g = 60\cdot \dfrac{2}{5} = 24

Consider these three squares with known area. 3 squares. The smallest square is labeled 25, the next square is 144, and the larg
Neko [114]

Answer:

The answer is "5, 12, and 13".

Step-by-step explanation:

Please find the complete question in the attached file.

The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.

The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:

C^2=A^2+B^2

And even those squares do verify the equation:

169 = 144 + 25

So, it's a rectangular (right) triangle, with sides spanning 5, 12, \ and \ 13.

What is the perimeter of a square whose diagonal is 3 radical 2
k0ka [10]

a square is made up of 2 congruent right triangles with the same leg length. we use the Pythagorean theorem to find the length of one of these legs. a^2+b^2=c^2, but we know that the legs are equal in length, so we have 2a^2=(3rad2)^2

2a^2=9*2

a^2=9

a=3

square is made up of 4 of these, so 4*3=12

the perimeter is 12

1. 12x^2-8x
larisa [96]

Answer:

Step-by-step explanation:

1) the two members of the expression has 4x in common, so we can rewrite it as: 4x(3x-2)

2) we have to find two numbers that multipied give -36 and that added up give 5

the two number are 9 and -4

we can rewrite the expression as : (x+9)(x-4)

3) we have to solve the associated equation

3x^2+10x+8 = 0

Δ/4 = 25-24 = 1

x1 = (-5+1)/3 = -4/3

x2 = (-5-1)/3 = -2

now we can rewrite the expression as

3(x+4/3)(x+2) = (3x+4)(x+2)
