2 9/10 if you round it up but if it is not then its 2 4/5
Answer:
x=2.25hrs
Step-by-step explanation:
1/9 =1/4hr
9/9=x
(9/9)/(1/9)=1/4.xhr
1/9=1/4.xhr
cross multiplying
4x=9
x=9/4
x=2.25hrs
Answer:
A. 6x^3 - 24x^2 + 6x + 36.
Step-by-step explanation:
(2x - 6)(3x^2 - 3x - 6)
= 2x(3x^2 - 3x - 6) - 6(3x^2-3x-6)
= 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36
Simplifying like terms:
= 6x^3 - 24x^2 + 6x + 36 (answer).
Answer:
12 units
Step-by-step explanation:
To find any side length of a right triangle given two side lengths, you would use the pythagorean theorem which is a² + b² = c². In this equation, a and b represents either the height of base of the triangle, and c represents the hypotenuse of the triangle (the diagonal line - in your question it is 13). By plugging in the base and hypotenuse, you get the equation of 5² + b² = 13². 5² is equal to 25 and 13² is equal to 169, so the equation is 25 + b² = 169. Subtract 25 for both sides of the equation and you find that b² = 144. Square both sides and the missing length is 12 because √144 = 12.
Y+y+17+111+90=360
2y+128+90=360
2y=360-218
2y=142
y=142/2
y=71
thus, the angles are 71, 90, 111, 88.
