Answer:
91 cm^2
Step-by-step explanation:
The bottom rectangle has an area of
A = l*w = 5* 14 =70
The top right rectangle has an area of
A = 3 *7 = 21
Add the areas together
A = 70+21 = 91 cm^2
y=-7x-6
-3 i tired to make it a fraction
Step-by-step explanation:
just solve for the formula y= mx +or- b
Answer:
5x^2−10x−2
Step-by-step explanation:
I hope this is what you are looking for I just added (5x^2 – 9) + (-10x + 7)
Answer:
9
Step-by-step explanation:
9v = 9(2i + 9j) = 18i + 81j
|9v | = 
= 
= 9
For a solution of 'all real numbers' to occur, you must end up with a statement that is true no matter what
example
simplifying results in x=x or 8=8 or 0=0 or something liek that
an example equation would be 2(x+1)=2x+2, simplifies to x=x or 2=2 or 0=0
no solution is when you get a false statement from simplifying
example, 3=4 or -1=0
an example equation could be 2(x+1)=2x+3, it simplifies to 2=3 which is false
