Answer:
Dimensions are 12 , 5
Step-by-step explanation:
Area of rectangular mural = length * width
length * width = 60 square feet
(x + 10)(x + 3) = 60
Use FOIL method
x*x + x*3 + 10*x + 10*3 = 60
x² + <u>3x + 10x</u> + 30 = 60 {Combine like terms}
x² +<u> 13x</u> + 30 - 60 = 0
x² + 13x - 30 = 0
Sum = 13
Product = -30
Factors = 15 , -2 (15+ (-2) = 13 ; 15*(-2) = -30)
x² + 15x - 2x - 30 =0 {Rewrite middle terms}
x(x + 15) - 2(x + 15) = 0
(x + 15)(x - 2) =0
x - 2 = 0 {Ignore (x +15) as dimensions wont have a negative value}
x = 2
x + 10 = 2 + 10 = 12
x + 3 = 2 + 3 = 5
Dimensions are 12 , 5
I dont know what you mean by the question but according to me.
If y=x^5
y=x^5+3
Then y+3=x^5+3

Answer:
Step-by-step explanation:
Given that Jared invested some money in a company's stock. Luckily for Jared, the company became very popular and the value of Jared's investment this morning is 7 times as large as the value of his investment yesterday morning.
a) Suppose Jared invested amount P
Today its value is 7P
i.e. 700% of yesterday value is value of Donald's investment this morning
b) Increase in value in one day from yesterday to today = 6 times P
i.e. increase in percent = 600%
Change in investment = +600%
15 x .06 = 0.9
Sales tax is 0.9 on a $15.00 item.
