Answer:
The area of the traiangle=Area of both traingle
=1/2×4.4×6.1 +1/2×4.4×3.3
=2.2×6.1+2.2×3.3
=2.2(6.1+3.3)
=2.2×9.4
=20.68in^2

you 0.04 times 300 then subtract 12-300
Answer:
The numbers are: 1 and 3.
Step-by-step explanation:
Let the first number be and the second number be .
Given: The difference between twice the number and the second number is . writing this mathematically,
From the second statement we get:
Solving for and we get:
and
Thus the first number is 1 and the second number is 3.
Answer:
The third number is 1/60
Step-by-step explanation:
Let the denominator of the number = x
1/4 + 1/3 + 1/x = 1/5
1/4 + 1/3 = 3/12 + 4/12 = 7/12
The lowest common denominator is 60x.
(7/12 + 1/x)/3 = 1/5 Remember that this is the average of 3 numbers. That's what the 3 is doing on the left. Multiply both sides by 3
7/12 + 1/x = 3/5 Multiply through by 60x
35x + 60 = 36x
x = 60
Very nice problem. Thanks for posting. This problem is a little involved. If you have trouble with it, leave a note in the comments and I'll come back and discuss it.
Answer:
strictly speaking ... poly means MANY
3x+ 4 is a binomial (bi = 2 parts)
with only one part it can not be described as a "POLY-nomial"
