So what we do is
area that remains=total area-triangle area that was cut out
we need to find 2 things
total area
triangle area
total area=rectange=base times height
area=(3x+4) times (2x+3)
FOIL or distribute
6x^2+8x+9x+12=6x^2+17x+12
triangle area=1/2 times base times height
triangle area=1/2 times (2x+2) times (x-2)=
(x+2) times (x-2)=x^2+2x-2x-4=x^2-4
so
total area=6x^2+17x+12
triangle area=x^2-4
subtract
area that remains=total area-triangle area that was cut out
area that remains=6x^2+17x+12-(x^2-4)=
6x^2+17x+12-x^2+4=
6x^2-x^2+17x+12+4=
5x^2+17x+16
area that remains is 5x^2+17x+16
Answer:
The center of the circle is
Step-by-step explanation:
Let the equation of the circle be
, where (-a,-b) is the center of this circle.
The points lying the circle must satisfy the equation of this circle.
A(0,0)
We substitute this point to get;
B(-3,0)
But c=0
C(1,2)
Put the value of 'a' and 'c' to find 'b'
b=-2
Hence the center of the circle is
Answer:
a squared plus b squared = c squared
Step-by-step explanation:
a) 100
b) 153
Honestly I'm just guessing i'm only in algebra 1 and even if i wasn't I suck at geometry
Answer:-15
Step-by-step explanation:
Answer:
2 cars
Step-by-step explanation:
105 + 895 + 1120 = 2120
He has to pay 2120 of downpayment
2120 - 1919 = 201
Subtract what he already has
He needs 201 more dollars to rent his first apartment
He needs to do 1.21818182 cars...
You cant do 1/5 of a car so he has to do 2 cars
