Answer:

-1

Step-by-step explanation:

We need to simplify the given expression . The given expression is ,

$\rm\implies ( 2 \sqrt6 +5)^{2n-1} ( 2\sqrt6 - 5)^{2n-1}$

Here we can see that the power of the both exponent is same that is (2n+1) . Recall the property of exponents ,

$\bf\implies a^m \times b^m = (ab)^m$

Using this property , we have ,

$\rm\implies ( 2 \sqrt6 +5)^{2n-1} ( 2\sqrt6 - 5)^{2n-1}$

This can be written as ,

$\rm\implies\{( 2 \sqrt6 +5) ( 2\sqrt6 - 5)\}^{2n-1}$

Simplifying using ( a+b)(a-b) = a² - b² ,

$\rm\implies\{( 2 \sqrt6)^2 -5^2 \}^{2n-1}\\\\\rm\implies ( 24 - 25)^{2n-1}$

Subtracting the numbers inside the brackets ,

$\rm\implies (-1)^{2n - 1 }$

Now we know that every odd number is in the form of 2n -1 , where n is any integer. Therefore , the power is odd .

Since the base is (-1) , for even power it is 1 and for odd power it is -1 . Therefore the final answer is ,

$\rm\implies\boxed{\quad \red{ -1 }\quad }$

Hence the required answer is (-1) .

Mark plans on taking 3 trips this summer. He'll drive 143 miles,138 miles , and 141 miles. Estimate the total miles he'll drive.

Deffense [45]

Lets round each distance to the nearest tens place, and then add them up to get an estimate. 143 rounds down to 140, 138 rounds up to 140, and 141 rounds down to 140. So: 140 + 140 + 140 = 420 miles

Answer:

A. g=11

Step-by-step explanation:

We want to find which choice makes the equation true. Let's plug in each answer choice.

A. g=11

26=7(11-9)+12

26= 7(2)+12 Solve inside the parentheses.

26= 14+12 Multiply 7 and 2.

26= 26 Add 14 and 12.

This answer must be correct, but let's check the other choices .

B. g=12

26=7(12-9)+12

26= 7(3)+12 Solve inside the parentheses.

26= 21+12 Multiply 7 and 3.

26≠33 Add 14 and 12.

This choice is not correct.

C. g= 13

26=7(13-9)+12

26= 7(4)+12 Solve inside the parentheses.

26= 28+12 Multiply 7 and 4.

26≠40 Add 28 and 12.

This is also not correct.

D. g= 14

26=7(14-9)+12

26= 7(5)+12 Solve inside the parentheses.

26= 35+12 Multiply 7 and 5.

26≠47 Add 35 and 12.

This choice is not correct either.

The value of g that make the expression 26=7(g-9)+12 a true statement is A. g=11.
