98%, Just add all of the numbers up to find the original average, then try to get the average up to what you want it to be.
The top base is : 14mm
The bottom base is: 36mm
The height is: 15mm
First you need to add the top and bottom bases together and divide it by 2
(14mm + 36mm) / 2
= 50mm/2
=25mm
Then you need to times it by the height
25mm x 15mm = 375mm^2
Answer:
<h3>
-58, -57, -56</h3>
Step-by-step explanation:
x - the first of consecutive integers
x+1 - the second of consecutive integers
x+2 - the third of consecutive integers
x+x+2 - sum of the first and third integers
3(x+x+2) - three times the sum of the first and third integers
3(x+x+2) = -342
÷3 ÷3
2x + 2 = -114
-2 -2
2x = -116
÷2 ÷2
x = -58
x+1 = -58 + 1 = -57
x+2 = -58 + 2 = -56
Answer:
Step-by-step explanation:
We know that x=3 is the solution to x-3=0 and x=-4 is the solution to x+4=0, thus:
