1. A rectangle has a length that is three feet more than twice its width.
(a) If the width of the rectangle is represented
by the variable w, give an expression for
the length of the rectangle in terms of w.
(b) What would the perimeter of this
rectangle be if the width was 10 feet?
(c) The perimeter of the rectangle is 78 feet. Set up an equation using w that models this
situation. Solve it and state the values for both the width and the length of the rectangle.
Part a: Expression for length; l = 2w + 3.
Part b: Perimeter equation; P = 2(l + 10).
Part c: Length of rectangle = 29 feet.
What is defined as the rectangle?A rectangle is a the kind of quadrilateral, a two-dimensional shape with four sides as well as four vertices. The rectangle's four angles are all right angles as well as equal to 90 degrees.The given conditions are-
Let 'l' be the length of the rectangle.
Let 'w' be the width of the rectangle.
Part a: expression for the length of a rectangle in the terms of w.
Length is three feet more than twice its width.
l = 2w + 3
Thus, the expression of l in terms of w is: l = 2w + 3.
Part b: Perimeter equation.
The width is given as 10 feet.
The formulae of perimeter if rectangle is;
P = 2(l + w)
Put the value;
P = 2(l + w)
P = 2(l + 10)
Thus, the equation for perimeter is P = 2(l + 10)
Part c: Length of rectangle.
perimeter of rectangle = 78 units.
P = 2(l + w)
w = 10 feet.
78 = 2(l + 10)
l + 10 = 39
l = 29
Thus, the length of the rectangle is found as 29 feet.

What is the linear equation formula?A linear equation's slope-intercept form is y = mx + b. The variables in the equation are x as well as y. The integers m and b represent the the line's slope (m) and the value of y when x is 0 respectively (b). Because (0,y) is the point when the line crosses the y-axis, the value of y when x is 0 is known as the y-intercept.
Which equations are linear?A linear equation with one variable is one with only one variable. It has the formula Ax + B = 0, where A and B can be any two real numbers as well as x is an unknown variable with a single solution. 9x + 78 = 18, for example, is a one-variable linear equation.
According to the given data:y = 70 + 18(x)
x = 12 batches.

2. Let f(x) = x4 + 2x3 - x² - 2x + 10. Given that one root of f(x) is 1 + i find all other roots.
All the roots of equation x⁴ +2x³ -x² -2x +10 are: (1 + i), (1 - i), -2i, 2i
In the given question, we have to find out all the roots or solutions for the equation x⁴ +2x³ -x² -2x +10. One of the roots given for this equation is 1+i
According to the 'Complex Conjugate' pairs, if an equation has a complex number as a root then its conjugate will also be a root of the equation.
So, we get z = 1 + i as a root then z* = 1 - i which is the conjugate of z, and z* will also be a root of the equation.
Also, the product of two roots will also be a root of the equation. So,
we know that, x = 1 + i, x = 1 - i, we get their product:
(x -(1 + i))*(x - (1 - i)) => by solving we get => x² -2x +2 = 0
=> x² -2x +1 = 1 => x² -x -x +1 = 1 (by middle term split)
=> x(x-1) -1(x-1) = 1 => we get (x - 1) as a factor
So, (x - 1) = 1 => x = 2
=> x = -2i, we get x = -2i
Again, by Complex conjugate pairs if x = -2i is a factor then it's conjugate x = 2i is also a factor.
Hence, the roots of the equation are: (1 + i), (1 - i), -2i, 2i

Find the y-intercept of the line on the graph
Since no equation of the line, or graph is provided in the question statement, considering the line to be [3x +4y = 12], the y-intercept of the line is 3.
As per question statement, we are supposed to determine the y-intercept of the line on the graph, but no equation of the line, or graph is provided. Hence, we considered the equation of a random line, say,
[3x +4y = 12] and then, determine it's y-intercept.
To solve this question, we can use two methods:
One method is by converting the given equation into the format of the standard equation of a line, and then comparing it to the standard equation to determine the y-intercept, i.e.,
The standard equation of line is (y = mx + c), where, "m" is the slope of the line, and "c" is the y-intercept. Converting [3x +4y = 12] to the form of the standard equation, we get,
[tex]3x+4y=12\\or,4y=-3x+12\\or,y=\frac{-3x+12}{4}\\ or,[y=(\frac{-3}{4})x+3]...(i)[/tex]
Now comparing (i) to the standard equation of line, we can identify that
(c = 3), i.e., y-intercept of the line [3x +4y = 12] is 3.
Another way we can determine the y-intercept of a line is by, substituting (x = 0) and then solving the equation for "y".
Y-Intercept: The y-intercept is the point on a cartesian plane, where a graph crosses the y-axis, i.e., the value of y when (x = 0).To learn more about Y-Intercepts, click on the link below.
