Hello There!

7d² + 10
7(3)² + 10
3² = 9
7 x 9 = 63

7d^{2}+10

Put the value of d (3) in the expression-
7(3)^{2}+10
Then solve the expression using the order of operations (PEMDAS)
There are no parenthesis with expressions so solve the exponent-
7(3)(3)+10
7(9)+10
Multiply before adding-
63+10
73

The answer to this expression is 73

A jug contains 6 qt of killa kola. kyle drank 3/10 of the jug. how much did he drink
jekas [21]

Answer:

Kyle drank 1.8 quarts of the jug.

Step-by-step explanation:

The quantity that Kyle drank from the jug is to equivalent to the product of the volume of the jug and portion that Kyle used. That is:

V_{dr} = \frac{3}{10}\cdot V_{jug}

Where:

V_{dr} - Volume that Kyle drank, measured in quarts.

V_{jug} - Volume of the jug, measured in quarts.

If V_{max} = 6\,qt, the volume drank by Kyle is:

V_{dr} = \frac{3}{10}\cdot (6\,qt)

V_{dr} = 1.8\,qt

Kyle drank 1.8 quarts of the jug.

Help please, and explain.
Korvikt [17]

Answer: 2x + y

<u>Step-by-step explanation:</u>

logₐ(3) = x

logₐ(5) = y

logₐ(45) = logₐ(3²· 5)

             = logₐ(3)² + logₐ(5)

             = 2 logₐ(3) + logₐ(5)

             = 2     x      +   y        <em>substituted given values (stated above)</em>
