KU and UM are equal to each other.
KU = 3x + 3
UM = 4x - 4
3x + 3 = 4x - 4
3x = 4x - 7
-x = -7
x = 7
If you plug that into either one of the equations, you get 24.
3(7) + 3
24
So depending on your question, x is 7, KU is 24, and UM is 24.
Answer:
Triangle c and e are right angled.
Step-by-step explanation:
Scalene triangle ( all sides are unequal )
Issocles triangle (two sides are equal )
Equilateral triangle ( all sides are equal)
i believe (x,y) will turn into (y,-x), so your answer is (5,-2)
<span>x+5y=8 ----------------- (1)
</span>y=3x ----------------- (2)
Substitute (2) into (1):
x + 5(3x) = 8
Distribute 5:
x + 15x = 8
Combine like terms:
16x = 8
Divide both sides by 16:
x = 0.5
Substitute x = 0.5 into (2):
y = 3(0.5)
Distribute 3
y = 1.5
Answer: x = 0.5, y = 1.5
Substituting for r and h:-
volume = pi (x - 3)^2 * (2x + 7)
= pi* (2x + 7)(x^2 - 6x + 9)
= pi * (2x^3 - 12x^2 + 18x + 7x^2 - 42x + 63)
= (2x^3 - 5x^2 - 24x + 63) pi answer
