Answer:
18
Step-by-step explanation:
7 - 5 = 2
triangle = bh/2
triangle = 2(3) / 2
triangle = 3
rect = bh
rect = 3 x 5
rect = 15
trapezoid = 15 + 3
trapezoid = 18
Answer:
21 because there is a 1/4 chance and there are 84 questions, so 1/4 (25%) of 84 is 21.
Step-by-step explanation:
Answer:

Kelly is correct.
Step-by-step explanation:
One person is able to plant 4 trees
Let x be the number of people
y be the number of trees
The situation is represented by

5 people are able to plant 20 trees

So, the situation is represented by 
Hence, Kelly is correct.
Slope of the line =
.
y-intercept of the line = -7.
Solution:
General form of equation of a line:
y = mx + c
where m is the slope and c is the y-intercept of the line.
Equation of a line:

To compare this with general equation.


Slope of the line =
.
y-intercept of the line = -7.
Answer:
All potential roots are 3,3 and
.
Step-by-step explanation:
Potential roots of the polynomial is all possible roots of f(x).

Using rational root theorem test. We will find all the possible or potential roots of the polynomial.
p=All the positive/negative factors of 45
q=All the positive/negative factors of 3


All possible roots

Now we check each rational root and see which are possible roots for given function.




Similarly, we will check for all value of p/q and we get

Thus, All potential roots are 3,3 and
.
