<span>8*11 + 6y = 28
88 + 6y = 28
6y = 28 - 88
6y = -60
y = -60/6
y = -10</span>
Answer:let
Length =L
Width =W
L=5W
Perimeter(p)=2L+2W
P=10W+2W
84=12W
Divide both sides by 12
W=7m
L=5*7=35m
Hence, the length and width are 35m and 7m respectively
Step-by-step explanation:
Answer:
105 dollars after a year
Step-by-step explanation:
I = (100)(0.05)(1)
I = 5
<u>c) 3, 6, 9 12</u> is NOT a geometric progression
<h3>Further explanation
</h3>
Geometry sequences are series of numbers that have a constant ratio
or can be interpreted:
Each number is obtained by multiplying the previous number by a constant
The sequence can be:
a, ar, ar², ar³, ... etc.
Can be formulated
where:
a is the first term, and
r is the common ratio
So we have to see the series has the same ratio or not
