x=−4 or x=12
Step 1: Factor left side of equation.
Step 2: Set factors equal to 0.
x+4=0 or x−12=0
x=−4 or x=12
x^2 - 8x -48=0
add both x
-7x = 48
x = -7
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). Examples.
if you give me an example i will walk it through with you
41 2/3% or 41.66%, or whole number 43%
Circumference of a circle is calculated by the formula:
= Pie * diameter
= π * diameter
= 22/7 * 22
= 69.14 cm
Area of circle:
= Pie * radius ²
Radius = diameter/2
= 11 cm
Area = 22/7 * 11²
= 22/7 * 121
= 380.29 cm²
C, and x=30
Karen had a gift card for $150. She bought 3 gifts for her sisters. The gifts cost the same amount, x. After paying for the gifts, her gift card had a balance of $60.
The rate is the ratio that makes the comparision between two quantities that are different to each and contains diffeent kind of measuring units
It also provide the information like feet per second, miles per hour, etc
So the ratio that makes the comparision between the different kind of units is known as rate
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.
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
