Answer:
4d - 6
Step-by-step explanation:
-2-(-15d)+(-11d)+2-6
-2 + 15d - 11d + 2 - 6
15d - 11d - 2 + 2 - 6
4d - 6
First, you would subtract 3 from both sides. This would leave you with 4x^2-8x-3. Then you would multiply 4 and 3 to leave the x by itself. You would end up with x^2-8x-12. You would then factor it out. However, you cannot factor this out so you would have to use quadratic formula. Once you are done using the quadratic formula, you should be left with your answers as -8 + √112 / 2 and -8 - √112 / 2.
None.
The absolute value of something cannot be <em>negative</em>.
Answer:
H or (3.5,-3)
number two:
B and (3.5,5)
Step-by-step explanation:
We have been given an image of a trapezoid. We are asked to find the area of the given trapezoid.
We will use area of trapezoid formula to solve our given problem.
, where,
A = Area of trapezoid,
a and b = Parallel sides or bases of trapezoid.
h = Height of trapezoid.
We can see that one base is 45 feet. The other base would be 45 plus 15 feet that is .
Now we will use Pythagoras theorem to find the height of the trapezoid as:
Therefore, the area of the given trapezoid is 420 square feet.
