the length of a rectangle is 3 times the width. the perimeter is 52 cm. find the length and width.

Step-by-step explanation:

156 , 52 times by 3 is 156

w=6.5cm and l=19.5cm

Step-by-step explanation:

l=3w & p= 52cm

P=2(l+w)

p=2(3w+w)

p=2(4w)

52cm=8w dividing both sides by 8

w=6.5cm

L=3w

L=3(6.5cm)

L=19.5cm

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
