Answer:

$1) - 2n + 14$

$2)- 5n + 30$

Step-by-step explanation:

$n = a + (n - 1) \times d \\ = 12 + (n - 1) \times - 2 \\ = 12 - 2n + 2 \\ = - 2n + 14$

$n = a + (n - 1) \times d \\ = 25 + (n - 1) \times - 5 \\ = 25 - 5n + 5 \\ = - 5n + 30$

PLZZ HELP ME WILL GIVE BRAINLIEST ( write in exponential form) 26*26^8

Lisa [10]

Answer:

26 * 26^8 = 26^9

Step-by-step explanation:

Here, we want to write 26 * 26^8 in exponential form.

26* 26^8 is same as 26^1 * 26^8

According to the first law of indices, we are going to add the powers together;

Thus, this gives ; 26^(1 + 8) = 26^9

Can someone Plzzz help me out???

Hello from MrBillDoesMath!

Answer: 3

Discussion:

The perimeter of a polygon is the sum of the side lengths.

Perimeter of top polygon is (x+2) + 2x + (x + 2) + (4x + 1) = 8x + 5

Perimeter of bottom triangle is 4x + 2x + (3x+2 ) = 9x + 2

The perimeters are the same when

8x + 5 = 9x + 2

Subtract 8x from both sides:

5 = (9x - 8x) + 2 or

5 = x + 2

Subtract 2 from each side to get x = 3:

5 -2 = 3 = x

The perimeter of either figure is 29
