Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
We have a=10, b=14 and c=18
a² + b² = 10² + 14² = 100 + 196 = 296
and
c² = 18² = 324
296 < 324 ⇒ obtuse triangle.
.......,.......The answer is B
Answer:
24th Day
Step-by-step explanation:
1.) Evaluate Data
Marco washes his car every 8 days. Marco fills his car with gas every 3 days. The question is asking when Marco will wash his car and fill it with gas.
2.) Solve
Find common factors for the two numbers:
3: 3, 6, 9, 12, 15, 18, 21, 24
8: 8, 16, 24
3 and 8 share 24 as a common factor.
3) Conclusion
Since the 3 and 8 share a common factor of 24 Marco will wash his car and fill it with gas every 24th day.
Answer:
Hello There!!
Step-by-step explanation:
1)x+4y=14
Add -4y to both sides.
x+4y+−4y=14+−4y
x=−4y+14
3)Add -7y to both sides.
3x+7y+−7y=22+−7y
3x=−7y+22
Step 2: Divide both sides by 3.
3x/3=−7y+22/3
x=-7y/3+22/3
hope this helps,have a great day!!

Answer:
540
Step-by-step explanation:
f(x) = x(x - 1)
g(x) = 3x
(f* g)(x) = x(x - 1)
3x
= (x^2 -x) * 3x
= 3x^3 -3x^2
=3x^2(x-1)
Let x = 6
(f* g)(6) = 3*6^2( 6-1)
= 3*36 *5
