Answer:
12, 8, and 4
Step-by-step explanation:
a + d + a + a - d = 24
3a = 24 ⇒ [ a = 8 ]
and (a + d)² + a² + (a - d)² = 224
3a² + 2d² = 224
2d² = 224 - 192 = 32
d² = 16
[ d = ±4 ]
∴ The first three terms to A.P are
a + d = 8 + 4 = 12
a - = 8
a - d = 8 - 4 = 4
∴ Three terms are 12 , 8, and 4
Answer:
h= 12.98 metres
Explanation:
The tree is leaning over so, the triangle is no longer right-angled.
Option 1 and option 4 are inversely proportional.
Inversely proportional means when one variable increases the other decreases in proportion.
Option 1 is true. When the number of tractors increases, the time to plow a farm decreases.
Option 4 is also true. If height is too large, base area should be too less to equalize the area.
Answer:
there are varous answer to this problem but the equation is 30+n
just plug in any number for n and add 30.
Ex:
