(I see that your concentrating on the task at hand with those YT and fortnite tabs open)
The area of the parallelogram is "base times height," so its 20*8 which is 160.
To find the area of the triangle, we have to find the base which incorporates Pythagorean'd theorem.
100 - 64 = 36, sqrt 36 is 6. So the base of the triangle is 6, the height is 12.6, thus the area is 6.3 * 6, which is 37.8
Adding the two values up, we get 37.8 + 160 = 197.8
Answer:
x = ± 5
Step-by-step explanation:
Given
x² - 4x - 25 = - 4x ( add 4x to both sides )
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ± 
= ± 5
Answer:
average speed = (55 + 70 + 525) / 6
= 650 / 6
= 108.33 km per hour
Step-by-step explanation:
first hour = 55 per hour.
= 55
second and third = 35 per hour.
= 70
fourth, fifth and sixth = 175 per hour.
= 525
average speed = (55 + 70 + 525) / 6
= 650 / 6
= 108.33 km per hour
