Area = (5x + 4)(4x - 4)
= 20x^2 - 20x + 16x - 16
= 20x^2 - 4x - 16 Answer

Step-by-step explanation:
bearing in mind that the slope goes by several names

however, is the same cat disguised with a different costume.
So, first what we should do is divide 2,046 by 62 to find the width of Lucas's banner.
2,046 / 62 = 33 The width of Lucas's banner is 33 cm.
Which means if the width of Emily's banner is 3x that:
3 x 33 = 99 Emily's banner is 99 cm in width.
So, your 2 answers are: 99 cm, division and multiplication. ;)
Answer:
r = 4/5
Step-by-step explanation:
Formula
Sum of an infinite geometric series = a / (1 - r)
Givens
Sum = 5*a
a = a
r = ?
Solution
5a = a/(1 - r) Divide both sides by a
5a/a = a / (a * (1 - r) The a's on the right cancel
5 = 1 / (1 - r) Multiply both sides by 1 - r
5*(1 - r) = 1*(1 - r)/(1 - r) The 1 - r s on the right cancel
5*(1 - r) = 1 Remove the brackets.
5 - 5r = 1 Subtract 5 from both sides
5-5 - 5r = 1 - 5 Combine
-5r = - 4 Divide by - 5
r = 4/5
