MY WORK:
First, you would cut it up into different parts/shapes
(I cut it up into rectangles)
Then, you would find the area of each.
The bottom rectangle: 10 ( 5 times 2 )
The middle rectangle: 12 ( 6 times 2 )
The top rectangle: 8 ( 4 times 2 )
Lastly, you would add!
10 + 12 + 8 = 30
Therefore, the answer is...
30!
My apologies if this is wrong but I hope I helped a little bit!
Answer:
Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means
In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:
Collect like terns
So, the equations are:
Total surface aera
1 big recangle and 2 triangles
rectangle has base of 3+4+5= 12
12*7=84
the 2 triangles
has base is 4
height of 3
2 of them
2*1/2*3*4=12
add total
84+12=96 in^2
1. 3/10
2. 1/10
3. -10/3
4. -10
Assuming you have to create an equation...
s is what you have to figure out so it is the subject of the rule
s=
you now need to find out what to do with the other side
you are taking 50 FROM 80 so
s=80-50
s=30
your answer is 30
