The answer is
C. - (x + 3)(x - 4)
because if you solve this....
- (x + 3)(x - 4)
(-x - 3)(x - 4)
-x^2 +4x - 3x + 12
-x^2 + x + 12
The formula for the area of a trapezoid is 1/2 (b1 + b2) h
So, take your b1 and b2, 12 and 6, and add them together. You get 18.
Divide this by 2, and you get 9.
Now, multiply 9 by your height, which is 4.
9 x 4 = 36.
The area of the trapezoid is 36 square inches.
Answer:
x=5
Explanation:
We need to get x to stand by itself on one side of the equation.
4x-2 = 3x+3 ← add 2 to each side
4x = 3x+5 ← subtract 3x from each side
x = 5 ← final answer
Answer:
should be 12.56
Step-by-step explanation:
the formula to find the area of a circle is A= πr2
so what you do is mulitply 3.14 ( number of pi) times radius (half of what the diameter is) squared which is the radius times the radius
3.14 x 2 x 2 + 12.56
Given:
The principal = $ 4000
The rate of interest = 22 %
To find the loan amount a) after 1 year and b) after 3 years.
Formula
Loan amount is
where,
A be the loan amount
P be the principal
r be the rate of interest and
t be the time.
Now,
a) Taking, P = 4000, r = 22, t = 1 we get,
or, 
Again,
b) Taking, P = 4000, r = 22 and t = 4 w eget,
Hence,
a) The amount of loan after 1 year is $ 4880
and b) The amount of loan after 4 year is $ 7263.39.
