None of the choices because none of the values of x is the same as the x value in 2x+3= 1/32

The expression n2 + n represents the total number of blocks used in the nth figure of a pattern. Use the equation n2 + n = 56 to

Brrunno [24]

We have to solve this quadratic equation $n^{2}+n=56$ for n to get which figure has 56 blocks.

$n^{2}+n=56\\n^{2}+n-56=0$

For middle term factorization, we need two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).

Such two numbers are 8 and -7. We can now write,

$n^{2}+n-56=0\\(n+8)(n-7)=0\\n=-8, 7$

"There is no negative figure number possible, so we disregard -8"

Our answer is 7.

ANSWER: The 7th figure has 56 blocks.

Answer:

135 degrees.

Step-by-step explanation:

Assuming that it is a regular octagon, you can use the formula (n-2) (180) divided by n. n = sides. Therefore, (8-2) (180) divided by 8, which is 135.
