Can someone explain this geometry problem? ? will give

the surface area of a cube is 600cm^2
what is the new surface area of the cube if the length of each edge of the cube is tripeled?

the answer is 5400^2 but i'm not sure how this is the answer? ?

Area is square units so if length is tripled (times 3), area is times 3^2 or 9  

so 600•9 = 5400 cm^2

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

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
