Answer:
x2 - 4x - 21
Step-by-step explanation:
Area = (x -7 )(x +3)
= x*x - 7*x + x*3 - 7*3
=x2 - 4x - 21
The answer to the question is $4.7
The first option is correct
Answer:
Slope is 5/3
y-intercept = -3
y = 5/3x - 3
Step-by-step explanation:
To find the slope, take to coordinates and use the equation below

7-2 = 5
6-3= 3
Now you have your slope which is 5/3
Then take the slope and input it into point slope form to get your y-intercept.
y-y₁=m(x-x₁)
y-2 = 5/3(x-3)
y-2=5/3x-5
add two to both sides to get Y by itself
y = 5/3x - 3
now you have your y-intercept, which is -3
Then check your answer by inputing two different coordinates for X and Y
7 = 5/3(6)-3
7=7
12= 5/3(9)-3
12=12
Answer:
I am not sure .but i will try
i think so i will give correct answer
perpendicular of triangle is 22-10 cm =12 cm bcz both sides of triangle are equal =22
area of rectangle l×w= 22×17=374
area of triangle =h×b/2 Now we r not having h
lets find it
use pythagorus theorum (h2=P2+b2....2 here is square)
h=22.5cm
22.5×19=427(area of triangle )
374+427=801cm sq
i tried my best dont know its righr of wrong
pls mark me as brainlieast
