Here you go mate
Use PEMDAS
Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction
Step 1
3(x-4)=12 Equation/Question
Step 2
3(x-4)=12 Remove parenthesis
3x-12=12
Step 3
3x-12=12 Add 12 to sides
3x=24
Step 4
3x=24 Divide sides by 3
answer
x=8
Hope this helps
The area of the trapezoid is calculated through the equation,
A = ((b₁ + b₂)/2) x h
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given above,
504 = ((18 + 30)/2) x h
The value of h from the equation is 21. Thus, Molly must make the trapezoid 21 inches high.
Answer:
The numbers for which the given property hold true are <em>12 </em>and <em>-7</em>
Step-by-step explanation:
Let the number be 
.
As per the given statement:
Square of the number (
) is 84 more than five times of the number (
).
Writing in the equation form:
To find:
All the numbers for which above equation holds true.
Solution:
Let us solve the above equation by rearranging the terms and then let us find the roots of the equation.
It is a quadratic equation(i.e. maximum power of is 2) so it will have 2 solutions i.e. 2 values of for which the above equation will hold true.
Let us factorize the equation.
So, the numbers for which the given property hold true are <em>12 </em>and <em>-7</em>.
