The area of a trapezoid is
A = (1/2) (h) (b1 + b2).
( 'h' is the height of the trapezoid. 'b1' and 'b2' are its two bases.)
You want the equation solved for one base.
A = (1/2) (h) (b1 + b2).
Multiply each side by 2 : 2A = h(b1 + b2)
Divide each side by 'h' : 2A/h = b1 + b2
Subtract b1 from each side: <em>2A/h - b1 = b2</em>
Answer:
a=8
Step-by-step explanation:
-5(a+3)=-55
First you times the bracket by -5
-5a-15=-55
Then you add the 15 to -55 because since the 15 is a negative on the right it has to be the opposite to the left
-5a=-40
Then you divide both sides by negative 5
-5a . = . -40
--------- ----------
- 5 -5
a= 8
Answer:
none of the above
Step-by-step explanation:
the answer is -3/4
Answer:
Step-by-step explanation:
An irrational number is a number that isn't a whole number (integer).
= 7.07
= 1
= 5
= 3
The first one is the only one that isn't an integer. So it is the answer.
