Step-by-step explanation:
Hello There!
The shown figure is a trapezoid
The formula for area of a trapezoid is
where a = base 1
b = base 2
h = height
the dimensions given are
13 & 7 - bases
5 - height
so all we have to do is plug in the values into the formula
So we can conclude that the area of the trapezoid is 50 cm²

Im unsure about g(f(4)) though.
Answer:
8x +5
Step-by-step explanation:
The sum is found by combining "like" terms—those that have the same arrangement of variables.
The first expression, 2x +6, has terms 2x and 6.
The second expression, 6x -1, has terms 6x and -1.
In each case, the first term listed is first-degree in the variable x. These are "like" terms, so can be added:
... 2x +6x = (2+6)x = 8x
The second term listed in each case is a constant. These are "like" terms, so can be added:
... 6 + (-1) = 5
Then the sum of the given expressions is the sum of the results from adding like terms:
... 8x + 5
Answer:
1
Step-by-step explanation:
Slopes of perpendicular lines are opposite reciprocal of one another i.e.
slope m1, of given line l1 = -1/slope m2, of its perpendicular line l2
slope m2, of its perpendicular line l2 = -1/slope m1, of given line l1
m2= -1/m1
Finding m1 from the given graph
m1= y2-y1/x2-x1
= -2-1/2+1
= -3/3
= -1
m2= -1/-1
= 1 !
