Answer:
Base = 32 cm
Height = 25 cm
Step-by-step explanation:
Area of a triangle can be calculated as:

We are given that the base of triangle exceeds the height by 7 cm. This can be expressed in an equation form as:
Base = Height + 7
Lets use B to represent base and H to represent height
B = H + 7
The equation of area can be stated as:

This is a quadratic equation which can be solved using a quadratic equation as shown below:

Since the height cannot be negative, we'll consider the positive value only i.e height is equal to 25 cm.
Therefore, the length of base will be 25 + 7 = 32 cm.
Answer:
No of these answers has a slope of
. My guess is B becasue its close to
unless the 5 is supposed to be negative
Step-by-step explanation:
You have to use the slope formula 
(
,
), (
,
)
(4, 0), (-2, 10)
you have to simplfy, the answer will be 
(10, -2), (0, 4)
you have to simplfy, the answer will be 
(4, 2), (10, 4)
you have to simplfy, the answer will be 
(-4, -10),(0, -2)
you have to simplfy, the answer will be 
Answer: D=22
Step-by-step explanation:
this is because if multiply f by r you get D and then you do all the other rmathematics and you wind up with 22
