The equation x² - 8x = 16 will equal to (x - 4)² = 32 so option (C) will be correct.
<h3> What is an expression?</h3>
An expression is a mathematical proof of the equality of two mathematical expressions.
Expressions are collections of variables, numbers, addition, subtraction, multiplication, and division.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given,
x² - 8x = 16
x² - 8x - 16 = 0
Add and subtract 16 to the left-hand side
(x² - 8x +16) - 16 - 16 = 0
(x - 4)² - 32 = 0
(x - 4)² = 32
Hence the expression (x - 4)² = 32 will equal to x² - 8x = 16 .

Answer:
(4,0) and ( 0,-4)
Step-by-step explanation:
The solutions are the the graphs intersect
There are two points
(4,0) and ( 0,-4)
Answer:
The sample observations are not a randomsample, so a test about a population proportion using the normal approximating method cannot be used.
Step-by-step explanation:
The necessary conditions are
The sample must be random and independently selected from the normally distributed population.
n*p and n*q both must be greater than 5
There must be two outcomes "success" and "failure"
The number of trials must be fixed.
From the given information 2), 3)and 4) conditions are satisfied, but not 1) because we are not given that people are selected randomly.
Answer: The sample observations are not a randomsample, so a test about a population proportion using the normal approximating method cannot be used.
Answer:
Step-by-step explanation:
10 students participated in a Mathematics quiz. If the number of girls is 4 more than the number of boys, find the number of boys and girls who took part in the quiz
Solution: Number of girls = x
Number of boys = y
x + y = 10 -------------------(I)
Number of girls is 4 more than the number of boys
x - y = 4 ----------------------(I)
x = 4 + y
Substitute x = 4 +y in equation (I)
4+ y + y = 10
4 + 2y = 10
2y = 10-4
2y= 6
y = 6/2
y = 3
Plug in y = 3 in eqution (I)
x + 3 = 10
x = 10 - 3
x = 7
Number of girls = 7
Number of boys = 3
