We can work out the first three terms of this quadratic equation with substitution.
The first term of this sequence is where n=1, we can substitute 1 in for n
y=1^2+2(1)-4
y=1+2-4
y=-1
We can do this for the next two terms as well
y=2^2+2(2)-4
y=4+4-4
y=4
For the last term:
y=3^2+2(3)-4
y=9+6-4
y=11

It takes 1 yard 2 feet of material to make a pillow. How much material is required to make 8 pillows?
Monica [59]

40 feet or 13 yards and 1 foot

using the conversion

1 yard = 3 feet then 1 yard 2 feet = 5 feet ← material for 1 pillow, hence

8 pillows require 8 × 5 = 40 feet

Find two consecutive integers whose sum is -29
LuckyWell [14K]

Example:

The sum of two consecutive integers is -15.  What is the product of the two integers?

x = 1st consecutive integer

x + 1 = 2nd consecutive integer   {consecutive integers increase by 1}


x + x + 1 = -15   {the sum of two consecutive integers is -15}

2x + 1 = -15   {combined like terms}

2x = -16   {subtracted 1 from each side}

x = -8   {divided each side by 2}

x + 1 = -7   {substituted -8, in for x, into x + 1}


-8 and -7 are the two consecutive integers


Their product is 56.
