\textsf{Rectangle A}

\implies \mathsf {Area = 3 \times 6 = 18cm^{2}}

\implies \bf {Yes}

\textsf {Rectangle B}

\implies \mathsf {Area = 2 \times 9 = 18cm^{2}}

\implies \bf {Yes}

\textsf {Rectangle C}

\implies \mathsf {Area = 5 \times 4 = 20cm^{2}}

\textsf {Rectangle D}

\implies \mathsf {Area = 9 \times 2 = 18cm^{2}}

\implies \bf {Yes}

Step-by-step explanation:

Let's solve one by one in order to get which has an area of 18cm²

We know that,

  • Ar(Rectangle) = l*b

We'll use this formulae.

Rectangle A:

  • l*b
  • (6*3)cm²
  • 18 cm²

Rectangle B:

  • l*b
  • (9*2)cm²
  • 18 cm²

Rectangle C:

  • l*b
  • (5*4)cm²
  • 20 cm²

Rectangle D:

  • l*b
  • (9*2)cm²
  • 18 cm²

Hence, Rectangle A,B and D Has an area of 18cm².

When the volume of a gas is
Fudgin [204]

Answer: The initial volume is 593.76mL

Step-by-step explanation:

As you do not say anithing about the pressure, i guess that the pressure remains constant.

If the gas is an ideal gas, we have:

P*V = n*R*T

where P is pressure, n is number of moles and R is a constant.

Now, initially we have:

P*Vi = n*R*315°C

finally we have:

P*825mL = n*R*452°C

Now we can take the quiotient of those two equations and get:

(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)

Now we have:

Vi/852mL = 315/452

Vi =  (315/452)*852mL = 593.76mL

So when we expand the gas at constant pressure, we increase the temperature.

Use the Distributive Property to solve the equation. 2x−4​(x−3​)=−8+5x-8
andrew11 [14]

Answer:

x = 4

Step-by-step explanation:

Distributive Property: a(b + c) = (a*b) + (a*c)

           2x - 4(x - 3) = -8 + 5x - 8

2x + x * (-4) - 3*(-4) = -8 + 5x - 8

          2x - 4x + 12  = -8 + 5x - 8    

   2x -  4x - 5x + 12 = -8 - 8

               -7x  + 12  = -16

                       -7x  = -16  -12

                      -7x   = -28

                          x = -28/-7

x = 4

The sum of two numbers is 16. One number is 3 times the other. Find the numbers.
Dimas [21]

Answer:

X = 12

Y = 4

Step-by-step explanation:

X + Y = 16

X = 3Y

3Y + Y = 16

4Y = 16

Y = 4

X + 4 = 16

X = 12
