Answer:
1368
hope this helps
have a good day :)
Step-by-step explanation:
This is the concept of algebra. Given that f(x)=3x+10x and g(x)=5x-3, then:
(f+g)(x)
=f(x)+g(x)
=3x+10x+5x-3
=18x-3
the answer is B. (f+g)(x)=(18x-3)
Answer:
option 2. mean is larger than median.
Step-by-step explanation:
mean of the set = ( 88+81+93+85+98)/5
= 445/5
= 89
median of the set = 88
the mean of the set is greater than the median.
Answer:
If The ratio of the width to
the length of a rectangle is 4:15
let width is 4x
let length is 15x
perimeter of the rectangle = 2(length + width)
= 2(15x + 4x)
= 2(19x)
=38x
If the perimeter of the rectangle is 152 meters.
152 = 38x
x= 152/38
x = 4
so,
width is 4x = 4(4) = 16m
length is 15x = 15(4) = 60m
The area of the rectangle = length. width
= 60m.16m
= 960 m^2
Step-by-step explanation:
The graph makes it evident that the axis of symmetry is the line x = 2. To algebrically show work, you’d need to use the formula x = -b/2a for a quadratic function in standard form. Remember, the axis is the vertex’s X value
