Answer: Equation

Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.

Answer:

- 2x - 31

Step-by-step explanation:

Given

- 3(4x + 5) - 2(- 5x + 8)

Multiply the terms in the first parenthesis by - 3 and the terms in the second parenthesis by - 2

= - 12x - 15 + 10x - 16 ← collect like terms

= (- 12x + 10x) + (- 15 - 16)

= - 2x - 31

Area = $\pi r^{2}$
area = $\pi$ x 1 x 1 = $\pi$

Circumference = $2\pi r$
Circumference = 2 x $\pi$ x1
Circumference = 2 $\pi$

The circumference is greater than the area

You need to divide the 3 blocks of clay by the 4 friends. 3 goes in the dividend and the 4 is outside. 3 divided by 4 is equal to 0.75 or 3/4, so each friend gets 0.75 or 3/4 clay
