Answer:
27
Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2 Multiply by 2
2Area = (b1 + b2)*h Divide by h
2Area/h = b1 + b2 Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27
It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.
Answer:
Step-by-step explanation:
6root = 6^2= 6 x 6
= 36
6root7 = 36 x 7 = 252
Also,
5xroot7 = 5 x 7^7
= 5 x 49
= 245
Therefore,
6root7 - 5xroot7 - Xroot7 = 0
252 - 245 - 7x^2
= 7- 7x^2
Hi , basically when we want to use negative numbers in real world problems , we should always put words like decrease , drops , less , because those words describe an explicit situation that describes subtraction , for example Ana is playing soccer with her friends , her score is less than 0 because she has been trying to mark a goal but she is unable to do it . The score of Ana is -5 , the score of her friend is -2 .
