Answer: 
Step-by-step explanation:
Given: The side of the square shaped traffic sign = 4x+3
We know that the area of square is given by:-

Therefore, the area of the side of the square shaped field is given by:-

We know that , 
Therefore,

Hence, 
Answer:
Step-by-step explanation:
Original Ratio = New Ratio All these problems are done the same way. Try to conquer the language.
The original ratio = 24 inches wide / 12 inches tall
Shawna's new ratio = you don't know / 2 inches in height (or tall)
Call what you don't know = x
24/12 = x / 2 Cross multiply
12 * x = 24 * 2 Combine the right
12 * x = 48 Divide by 12
12x/12 = 48/12
x = 4
So the new height is 4 inches.
the square of a negative number always be positive
eg: -2² = -2×-2 = (-×- = +) +4
the cube of a negative number always be positive
eg: -2³ = -2×-2×-2 = (-×-×- = +) -8
hope it helps...!!!
Step-by-step explanation:
The composite function (f o g)(x)
= f(x² - 5)
= 4(x² - 5) + 1
= 4x² - 19.
