Mathematics
1 answer:
pishuonlain [190]3 years ago
7 0

Answer:

m = -10, 14 x = 1, -5

Step-by-step explanation:

m^2 - 4m = 140 (in a parallelogram, opposite angles are congruent)

(1)m^2 - 4m - 140 = 0

Objective: Find two numbers that multiply to -140(1 * -140) and add to -4

Numbers: 10, -14

(m + 10)(m - 14) = 0

m + 10 = 0, m - 14 = 0

m = -10, m = 14

x^2 + 4x = 5 (in a parallelogram, opposite sides are equal)

(1)x^2 + 4x - 5 = 0

Objective: Find two numbers that multiply to -5(1 * -5) and add to 4

Numbers: -1, 5

(x - 1)(x + 5) = 0

x - 1 = 0, x + 5 = 0

x = 1, x = -5

Wilma drove at an average speed of 60 mi/h from her home in City A to visit her sister in City B. She stayed in City B 15 hours,
Triss [41]

Answer:

574.8 miles

Step-by-step explanation:

Given:

An average speed of Wilma from City A to City B =  60 miles per hour

She stayed in City B 15 hours.

An average speed of Wilma from City B to City A  =  35 miles per hour.

Whole time taken including 15 hours stay in city B = 41 hours

Question asked:

How many miles is City A from City B ?

Solution:

Total time taken including 15 hours stay in city B = 41 hours

Total time taken on the trip excluding stay in city B = 41 - 15 = 26 hour

Let time taken during from city A to city B = x

Time taken during from city B to city A = 26-x

As distance traveled from city A to city B is equal to distance traveled from  city B to city A:-

And by using : Distance=speed\times time

Distance traveled from city A to city B = Distance traveled from city B to A

speed\times time = speed\times time

60\times x=35(26-x)\\60x=910-35x

Adding both sides by 35x

95x=910

Dividing both sides by 95

x=9.58\ hours

Distance traveled from city A to city B = speed\times time

                                                               = 60 \times 9.58

                                                               = 574.8 miles

Therefore, there are 574.8 miles from City A to City B.
