Answer:
<em>The</em><em> </em><em>answer is</em><em> </em><em>29</em><em> </em><em>unit</em><em>.</em>
Step-by-step explanation:
Here,
given that,
DC (l) =4z+1
CD (b)=5z+2
perimeter (p)= 132
now,
perimeter of rectangle (p) is= 2(l+b)
or, 132 = 2×{(4z+1)+(5z+2)}
or, 132= 2×(9z+3)
or, 132= 18z+6
or, 18z=132-6
or, z=126/18
or, z= 7.
therefore, 4z+1=4×7+1=29
5z+2= 5×7+2=37.
As our question is about to find AB,
DC = AB. (as opposite side of rectangle is equal).
so, the valueof AB is 29unit.

Xy=130
y=3+x
x(3+x)=130
x²+3x-130=0
(x+13)(x-10)=0
x= -13 or 10
since the question says X and Y are positive we just dismiss-13
x=10
and y=13

Answer:
point-slope form;
(y - 1) = -8(x+2)
slope-intercept form;
y = -8x - 15
Step-by-step explanation:
The first step is to determine the slope of the given line;
8y = x − 4
y = 1/8(x) - 1/2..... After dividing both sides by 8
The slope of the line is thus 1/8, the coefficient of x when the equation is written in slope-intercept form.
The required line is perpendicular to this given line which implies that the product of the slopes will be equal to -1. Let the slope of the required line be m;
m * 1/8 = -1
m = -8
The slope of the required line is thus -8. Using the given point, (−2, 1), the equation of this line in point-slope form becomes;
(y - 1) = -8(x - -2)
(y - 1) = -8(x+2)
We make y the subject of the formula;
y = -8x - 16 + 1
y = -8x - 15
This is the slope-intercept form of the equation of the line.
Answer:
Step-by-step explanation:
The circumference of a circle in terms of the diameter is
If our diameter is 29 feet, then the circumference, in terms of pi is
.
If we are multiplying in pi as 3.14, then it is
C = 91.06 ft
The area formula for a circle is
If the diameter is 29, then the radius is half of that at 14.5 feet. Filling in:
so, in terms of pi, the area is
or if you multiply pi in as 3.14, then you get:
