Answer:
11
Step-by-step explanation:
(8y + 5) - 2z
y = 3, z = 9
Let's plug in the given values.
(8(3) + 5) - 2(9)
First let's multiply.
(24 + 5) - 18
Now simplify within the parentheses.
29 - 18
Subtract.
11
This is your answer.
Hope this helps!
Answer:
Length = x^2 = 0.835^2 = 0.698 m = 69.8cm
Breadth = x = 0.835 m = 83.5cm
Step-by-step explanation:
Given;
Length of the rectangular plot l = x^2 m
Breadth b = x m
Area A = 5832 cm^2 = 0.5832 m^2
(They should be converted to the same units before solving: length in metres and area in square metres)
The area of a rectangular plot can be calculated using the formula;
Area = length × breadth
A = l × b
Substituting the values of l and b;
A = x^2 × x
A = x^3
Substituting the value of A;
0.5832 = x^3
solving for x;
x = (0.5832)^(1/3)
x = 0.835 m
Length = x^2 = 0.835^2 = 0.698 m = 69.8cm
Breadth = x = 0.835 m = 83.5cm
