Answer:
<h3> -5n = 1 ⇒
n = -¹/₅</h3><h3> n+15 = (-10) ⇒ n = 25</h3><h3> n/5 = -1/5 ⇒ n = -1</h3><h3> n-13= -12 ⇒ n = 1</h3>
Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1
Answer:
The dimension of the plot is 30 yd by 20 yd
Step-by-step explanation:
Given;
Area = 600 yd^2
Length = width + 10
l = w + 10 ......1
Area of a rectangular plot is;
Area A = length × width
A = l × w
Substituting equation 1;
A = (w+10) × w
A = w^2 + 10w
600 = w^2 + 10w
w^2 +10w -600 = 0
Solving the quadratic equation;
w = -30 or 20
cannot be negative
w = 20 yd
l = w+10 = 20+10 = 30yd
The dimension of the plot is 30 yd by 20 yd
What don’t you understand
The length of the actual pen is 20 meters.
The scale drawing is a reduced form of an original image. The scale drawing is reduced by constant dimensions. In this question, the scale is 5cm : 2m. This means that on the scale drawing, 5cm represents 2m.
Length of the actual pen = (length of the pen on the scale drawing x 2m) / 5cm
(50 x 2) / 5
100 / 5
= 20 m
