Answer:
<u>416 square centimeters</u>
Step-by-step explanation:
Formula for finding area of a trapezoid :
<u>A = 1/2 x (a + b) x h</u>
- a and b = parallel sides of the trapezoid
- h = height of the trapezoid
Solving :
- A = 1/2 x (38 + 14) x 16
- A = 8 x 52
- A = <u>416 square centimeters</u>
Answer:
The unknown number is 66.
Step-by-step explanation:
We know that we need to find the number that is 55 when calculated as 5/6 or the whole number. First, we must divide 55 by 5.
55 ÷ 5 = 11
This means that 1/6 of the unknown number is 11.
Now, let's multiply 11 by 6.
11 x 6 = 66
Therefore, the unknown number is 66.
Hope this helps! :)
First, in order to know the surface area, you need to know the length and width as well, not just the hight.
First you need to find the X You know that since its a parallelogram opposite sides are congruent so you would do the following equation
(The work below goes vertical)
2x+3=3x-1
-3x-3I-3x-3
---------------
-x =-4
/-1 /-1
----------------
x= 4
So now that we know x=4 we plug it into the side
4+2=6
Then you multiply is by two since df goes across the whole shape and u get 12
Hope that helps
Step-by-step explanation:
a parabolic graph is given by the equation ax^2 + bx + c
the axis of symmetry is equal to -b/(2a)
however it is worth noting that all parabolas have a y intercept since their domain is all real numbers.
