Answer:
Option a and b both are correct.
Step-by-step explanation:
We have been given the information that is: n is added to 15 less than 3 times itself.
The result is 101.
So, the number is 15 less than 3 times to itself means: 3n-15
And n is added to it that means:
n+(3n-15)
And its result is 101 so,
n+(3n-15)=101
After simplification of above expression gives:
4n-15=101.
Therefore, Option a and b both are correct.
Answer:
255.61 inch³
Step-by-step explanation:
Volume of sphere is given by
V = πr³
Given that the original sphere had a radius of 5 cm, and that this is enlarged by a scale factor of 2, the new radius is
r = 5 cm x 2 = 10 cm
since 1 cm = 0.3937 inches, (need to convert to inches)
10 cm = 3.937 inches
hence r = 3.937 inches
V = x π x 3.937³
= 255.61 inch³
Answer:
algebraic expression. you have to solve for x. there is one term. the coefficient is 5. five times x plus ten
Step-by-step explanation:
The enlarged flower bed is a rectangle and its area is x^2+9x+14 m²
So before its enlargement by 14 m², the area of the rectangle = x^2+9x
As you know, the area of rectangle is equal length times width
so area = x^2+9x
factors:
x^2+9x = x (x + 9)
So the dimensions are x and (x + 9)
