Answer:I don’t write English you should translate
Áp dụng tính chất của đường trung bình ta có:
20+x=2.(2x+22)
20+x=4x+44
X-4.x=44-20
-3.x=24
X=24/-3x=-8
Trong độ dài ko có độ âm nên tất cả đại lượng hình học đều mang dấu (+) vì vậy kết quả cuối cùng sẽ là 8
Step-by-step explanation:
The original price of socks was $8.
Step-by-step explanation:
Caitlyn buys a shirt and a pair of socks on sale for 25% off.
The price of the shirt before the sale was $24 that means after discount the price was:
24 - (0.25 x 24) = $18
And Caitlyn paid a total of $24.
That means the price of socks after discount is = 24 - 18 = $6
Let the original price of socks be x. And after 25% discount, it was for $6.
So, x - 0.25x = 6
=> 0.75x = 6
x = 8.
Answer:
2nd option
Step-by-step explanation:
Given
3x³ - 15x² - 4x + 20
step 1 ( group the first/second and third/fourth terms )
(3x³ - 15x² ) + (- 4x + 20)
step 2 ( factor each group )
3x² (x - 5) - 4(x - 5) ← note factor of - 4 ( not + 4 )
step 3 ( factor out (x - 5) from each term )
(x - 5)(3x² - 4)
Answer:
6000π m²/h
Step-by-step explanation:
Area of the circular cloud =πr²----------------------------------------- (1)
Radius as a function of time = R(t)=50+20t------------------------ (2)
dA/dt = (dA/dr) x (dr/dt)-----------------------------------------------------(3)
dA/dr = 2πr
dr/dt = 20
After 5 hours, the radius of the cloud will be :
R(5)=50+20(5)
= 150 meters
Substituting into (3)
dA/dt = 2π(150) x 20
= 6000π m²/h
