<u>Answer</u>
5 and -4
<u>Explanation</u>
If the two triangle are congruent then they have the same area.
20 = x² - x
x² - x - 20 = 0
x² - x + (1/2)² = 20 + (1/2)²
(x - 1/2)² = 20.25
x - 1/2 = √20.25
x - 1/2 = 4.5 or x - 1/2 = - 4.5
x = 4 1/2 + 1/2 x = -4 1/2 + 1/2
= 5 = -4
The values of x are 5 and -4.
Answer:
9/10
Step-by-step explanation:
Answer: 11/3 or 3 2/3
Step-by-step explanation:
Simple to do this as the 11 and 15 can be simplified as 1 goes in 11... 11 times and 5 goes into 15... 3 times. Thus 11/3.
Answer:
16 Miles/Hours
Step-by-step explanation:
Average speed is the total distance covered divided by the total time
In that case we have a distance of 4 miles
Time is 15 minutes and in order to convert from minutes to hours we divide by 60 and it becomes 0.25 hours
So 4/0.25 is 16 Miles/Hours
Answer:
9/5 miles in 1 hour
Step-by-step explanation:
As we are finding here the miles distance in 1 hour so we have to use here the formula which is
Rate = Distance / Time
Rate = 3/5 divided by 1/3
SO using third proportion rule we have to change the Numerator of second fraction with denominator and denominator with numerator and division sign will be change into Multiplication so this one will be
3/5 x 3/1
9/5 will be the answer
