Let's take this step by step. First, let's find the area of the triangle:
Small rectangle:
Big rectangle:
Let's add all the areas up:
So, your answer is:
The area of this figure is
92 cm².

Answer: 6a^3-6a^2b+3ab-3b^2</h3>
=============================================
Work Shown:
(2a^2+b)(3a-3b)
c(3a-3b) ..... let c = 2a^2+b
3ac-3bc .... distribute
3a(c)-3b(c)
3a(2a^2+b)-3b(2a^2+b) .... plug in c = 2a^2+b
3a(2a^2)+3a(b)-3b(2a^2)-3b(b) ... distribute
6a^3+3ab-6a^2b-3b^2
6a^3-6a^2b+3ab-3b^2
You could also use the FOIL rule to get the same result. The box method is a visual way to keep track of the terms.
32% of 25 is 8.
It would be formed some what like this but I'm not really sure
25/32*100
Correct me if I am wrong.
Answer:
R = -H + 24
Step-by-step explanation:
An antique dealer has 24 clock radios to sell 12 at a 12 hour long antique Radio sale
12 radios are sold in 12 Hour
Table
Hours Radio Available Remaining
0 24
2 22
4 20
6 18
8 16
10 14
12 12
Line of equation R = mH + c
R = Radios Available / Remaining to be sold
H = Hours of Sale passed
m = slope of line
c = constant
H = 0 , R = 24
24 = 0 + c
=> c = 24
R = mH + 24
for H =2 R = 22
22 = 2m + 24
=> m = -1
R = -H + 24
As every passing hour he will be able to sell a radio so number of radios available will keep decreasing so there is a sign of - multiplied by H
24 is the radio available at beginning of sale.
if we plot a graph for Radio sold against hours
then equation would be
R = H ( c = 0 as no radio sold at beginning of sale)
