Solution 1
Answer:
x=−4 or x=12
Step-by-step explanation:
Step 1: Factor left side of equation.
(x+4)(x−12)=0
Step 2: Set factors equal to 0.
x+4=0 or x−12=0
x=−4 or x=12
Solution 2

- Circumference = 69.14cm
- Area = 380.29cm²
Step-by-step explanation:
Circumference.
Circumference of a circle is calculated by the formula:
= Pie * diameter
= π * diameter
= 22/7 * 22
= 69.14 cm
Area
Area of circle:
= Pie * radius ²
Radius = diameter/2
= 22/2
= 11 cm
Area = 22/7 * 11²
= 22/7 * 121
= 380.29 cm²

Answer:
6x+19
Step-by-step explanation:
The parentheses do nothing here to stop you from adding - since every term in here is only being added, there is no reason to worry about the parentheses. Simply combine like terms (13 + 6) to achieve 6x + 19.
923000 is the number in which 9 represents 1/10th of its value in 92300.
What is the fundamental principle of multiplication?
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
we need to find the number in which 9 represents 1/10th of its value in 92300.
here, this number would be 10 times larger.
Multiply 92300 by 10
= 92300 x 10
= 923000.

Answer:
923000.
Step-by-step explanation:
You want to find the number in which 9 represents 1/10th of its value in 92300. Naturally, this number would be 10 times larger. Multiply 92300 by 10 to get 923000.
add 5 to both sides
y - 5 +:5 = 2/3x + 6 + 5
y = 2/3x + 11
the y intersept is 11 or (0 , 11) when x is 0
when x is 3
y = 2/3 (3) + 11 or 2 + 11 = 13
so a 2nd point could be (3 , 13)
