Let the variable of the equation be x.
Solution of the equation is given to us, hence,
x = -3 and x = 9
x + 3 = 0 and x - 9 = 0
Multiplying,
(x + 3)(x - 9) = x² - 9x + 3x - 27 = x² - 6x - 27
Hence, the linear equation with solution -3 and 9 is x² - 6x - 27.
Your answer would be B.
Step-by-step explanation:
$93 / 12 = $7.75
The area of a triangle with base 'b' and height 'h' is given by the formula:
It is given that the area of a triangle is 
.
It is given that the base of the triangle is 5 times the height.
So, 
We have to determine the height of the triangle.
Since, 
So, 
So, h = 24 cm
Therefore, the height of the triangle is 24 cm.
Option 2 is the correct answer.
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
From 100 to 999, all integers are three (3) digit numbers and available digits are (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
It implies that the total number of digits is 9. The next thing to do will be to arrange the 9 digits in three (3) places in such a way that repetition is allowed.
In the first place;
- the number of ways the number can be positioned since it can't be zero and seven = 8.
Hence, the first chance is 8 out of 10 chance.
In the second and third place;
∴
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is:
= 8 × 9 × 9
= 648
Therefore, the number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
