Answer:
Width = 5 inches
Length = 9 inches
Step-by-step explanation:
The paper;
Length = (x + 4) inches
Width = x inches
The area is close as possible to 50 square inches.
Since this paper is rectangular in shape; the area of a rectangle is given by:
Area = Length × Width
∴ (x + 4) * x = 50 square inches
x² + 4x = 50
Let the area be equal to 45 square inches;
Applying the quadratic formula, x = 5 or -9
But since we are dealing with length measurements, the value of x = 5 inches.
So the width = 5 inches and;
length = 5 + 4 = 9 inches.

Answer:
The equation which has ONLY two solution x = 3 and x = -3 is
Step-by-step explanation:
Here, the ONLY two rrots of the equation is given as:
x = 3 and x = -3
Now, if x = a is the ZERO of the polynomial, then x - a = 0 is the ROOT of the polynomial.
So, here the only roots of the polynomial are : (x-3) and (x+3)
Also, the POLYNOMIAL = PRODUCT OF ALL ROOTS
So,
Hence, the equation which has ONLY two solution x = 3 and x = -3 is
Answer:
3 units
Step-by-step explanation:
Answer:
y = 4 sin(t/2 + 4π/3) − 2
Step-by-step explanation:
General form:
y = a sin(2π/T t)
Given a = 4 and T = 4π:
y = 4 sin(2π/(4π) t)
y = 4 sin(t/2)
Add horizontal shift of -4π/3 and vertical shift of -2:
y = 4 sin(t/2 − (-4π/3)) − 2
y = 4 sin(t/2 + 4π/3) − 2
