Answer:
Area of trapezoid = 21 cm²
Step-by-step explanation:
Given:
Length of rectangular shape = 4 cm
Width of rectangular shape = 3 cm
Base of triangle = 3 cm
Number of triangle = 3 cm
Find:
Area of trapezoid
Computation:
Area of trapezoid = Area of middle rectangle + Number of triangle[Area of triangle]
Area of trapezoid = [l x b] + 2[(1/2)(b)(h)]
Area of trapezoid = [4 x 3] + 2[(1/2)(3)(3)]
Area of trapezoid = 12 + 9
Area of trapezoid = 21 cm²
Answer: Option c.
Step-by-step explanation:
The missing figure is attached.
Given a point
:
1. If it is reflected over the y-axis:
→ 
2. If it is reflected over the x-axis:
→ 
3. If it is rotated 180 degrees about the origin:
→ 
In this case, you can identify that the point A is:

Then:
If it is reflected over the y-axis:
→ 
If then it is reflected over the x-axis:
→ 
Finally, if this is followed by a rotationf of 180 degrees about the origin, this is:
→ 
A quadratic equation given roots is solved by using the relation

from the question,
sum of the root will be



and also, product of the roots will
be

now substituting the sum of roots and product of roots into the equation


as the quadratic equation for the root 3/4 and -4
(g-f)(x)=g(x)=f(x)
(g-f)(x)=6x-4+x^2
(g-f)(x)=x^2+6x-4 then:
(g-f)(3)=3^2+6*3-4
(g-f)(3)=9+18-4
(g-f)(x)=23
