Answer:

- The value of both expressions when t = 3 is 30

- The value of both expressions when t = 7 is 54

- The expressions are equivalent

Step-by-step explanation:

Plug in each value of t into the expressions:

6t + 12, when t = 3 equals 30

6t + 12, when t = 7 equals 54

6(t + 2), when t = 3 equals 30

6(t + 2), when t = 7 equals 54

We have the same answers for both expressions, meaning they are equivalent.

Answer: 3rd, 4th, and 5th are correct.

Step-by-step explanation:

We know that the equation 6(t+2) can be simplified to 6*t+6*2, also 6t+12. This causes any statements saying a variable with a certain value applies to one side also applies to the other.

Which is a reasonable first step that can be used to solve the equation 2 (x 6) = 3 (x minus 4) 5?

MAVERICK [17]

Multiply 2 to x 6 and multiply 3 to (x-4)5.

The Reasonable first step that can be used to solve the equation 2 (x 6) = 3 (x minus 4) 5,

2 (x 6 ) = 3(x-4)5

The reasonable first step is,

Multiply 2 to x 6 and multiply 3 to (x-4)5.

Hence, Multiply 2 to x 6 and multiply 3 to (x-4)5.

The Length of one side of a parallelogram is 3 more than twice the length of the adjacent side. The perimeter of the parallelogr

katovenus [111]

Answer: 4 cm and 11 cm.

Step-by-step explanation:

1. You can calculate the perimeter of a parallelogram as following:

$P=a+b+c+d$

Where a+b+c+d are the lenghts of the sides.

By definition the parallelogram has two pairs of parallel sides, therefore:

a=c and b=d

Then, you can calculate the perimeter as following:

$P=2(a+b)$

2. Let's call the adjacent side $x$ , then the other side is 2x+3.

3. Substitute values and solve for x:

$30=2(x+2x+3)\\30=2(3x+3)\\30=6x+6\\24=6x\\x=4$

4. Then the lenghts of the sides are:

$x=4cm\\2x+3=2(4cm)+3=11cm$

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.

KengaRu [80]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals $5^{10}$ or not

Take for instance:

$5^5 * 5^5$

Using law of indices:

$5^5 * 5^5 = 5^{5+5$

$5^5 * 5^5 = 5^{10$ ---- equivalent

$\frac{5^5 + 5^5}{2 * 5^{-5}}$

Factorize the numerator

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}$

Cancel out 2

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}$

Apply law of indices

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10$ ---equivalent

$125 * 78125$

Express as exponent

$125 * 78125 = 5^3 * 5^7$

Apply law of indices

$125 * 78125 = 5^{3+7$

$125 * 78125 = 5^{10$ ---- equivalent

$5^3 + 5^7$

Solve exponents

$5^3 + 5^7 = 125 + 78125$

$5^3 + 5^7 = 78250$ ---- not equivalent
