Answer:
Step-by-step explanation:
We have been given a graph of a rectangle. The area of the shaded section is 63 square units. We are asked to find the value of x.
We can see from our given graph that shaded section forms a trapezoid, so we will use area of trapezoid formula to find the value of x.
, where, a and b represents the parallel sides of trapezoid and h represents height of trapezoid.
Upon substituting our given values in above formula we will get,
Upon dividing both sides of our equation by 3.5 we will get,
Let us subtract 7 from both sides of our equation.
Therefore, the value of x is 11 units.
Answer:
The correct answer is option C.
Step-by-step explanation:
Let the number be x.
The square of a number exceeds that number by 12 .Mathematically can be written as:
Using middle term splitting to factorize the expression:
The two possible solutions are :
1) (x+3)=0
x = -3
2) (x-4)=0
x = 4
