Given:
QSR is a right triangle.
QT = 10
TR = 4
To find:
The value of q.
Solution:
Hypotenuse of QSR = QT + TR
= 10 + 4
= 14
Geometric mean of similar right triangle formula:

Answer:
(4)($3)
Step-by-step explanation:
Given parameters:
Quantity of mushroom bought = 4.25pounds
Cost of each mushroom = $2.99
Unknown:
Best estimate for the cost of the mushroom = ?
Solution:
The cost of the mushroom is:
Total cost = quantity of mushroom bought x cost of each mushroom
Total cost = 4.25 x 2.99
You can round 4.25 to 4 and 2.99 to 3
Or 4 x 3 = $12
A
you have to solve x^2+x-5=0
So x=(-1 +/- sqrt(1^2+4*1*5))/2
x=(-1 +/- sqrt(21))/2
