Answer:
3(c+4)
Step-by-step explanation:
It would usually be 3 x 4, but since there is a variable, it can`t be multiplied (unless you know what the value of the variable is). Thus the expression is 3(c+4).
Answer:
the fourth answer
Step-by-step explanation:
this is because 6 x 10 is 60, and is you multiply the height by 3 it gives you 3(6) x 10 which can also be written as 18 x 10 which is equal to 180
divide 180 by 60 which will give you 3, this shows you that the growth from the original area to the new area is 3 times, so the ratio is 3:1
An equal-sized spinner is used to model probabilities
The spinner should have 4 equal sections
The number of friends is given as:

When Elisondra is included, the total number of people that went to the restaurant is:

Substitute 3 for Friends

Add 3 and 1

The number of people that went to the restaurant is the number of equal sections of the spinner.
Hence, the spinner should have 4 equal sections

To find area we multiple length by width
20 times 45 is 900
then multiply that by 2 because there are two floors that are that size
900 times 2 is 1800
the total area for both floors is 1800 square feet
Let x be the length of the garden
and y be the width of the garden.
since you only enclose 3 sides of the garden by a 40 ft fence. so the equation for this is:
2x + y = 40
and the area of the garden is 100 sq ft, so in equation
xy = 100
from equation 1, 2x + y = 40
y = 40 - 2x
substitute to equation 2
xy = 100
x ( 40 - 2x) = 100
40x - 2x^2 = 100
2x^2 - 40x + 100 = 0
x = 2.9 ft
y = 34.5 ft
