Mathematics
1 answer:
katovenus [111]3 years ago
4 0

Answer:

x = 15

Step-by-step explanation:

Using the Altitude on Hypotenuse theorem

( leg of large Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )

Thus

x² = 9 × (9 + 16) = 9 × 25 = 225 ( take the square root of both sides )

x = \sqrt{225} = 15

X^2+ 17x+91=0<br> Help please!!
Morgarella [4.7K]

Answer:

x^2+17x+91=0

a = 1; b = 17; c = +91;

Δ = b2-4ac

Δ = 172-4·1·91

Δ = -75

Delta is less than zero, so there is no solution for the equation

if sarah rides her bike 5 miles north, then 3 miles east, what is the shortest distance she would have to travel to return to he
kykrilka [37]

Answer:

The answer to your question is the shortest distance is 5.83 mi

Step-by-step explanation:

Process

1.- We observe that the rides to north and after to east, so she is describing a right triangle where the shortest distance to come back to the starting point is the hypotenuse of that triangle.

                                 c² = a² + b²

                                 c² = 5² + 3²

                                 c² = 25 + 9

                                 c² = 34

                                 c = 5.83 mi
