Answer:
x^2-8x-9
x
2
−8x−9
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10)
Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
Answer: Second Option is correct.
Step-by-step explanation:
Since we have given that
In a parallelogram, the vector from one vertex to another vertex is (9,-2)
So, the co-ordinate of first vertex will be (9,0).
And the coordinate of second vertex will be (0,-2).
As we know the formula for "Distance between two coordinates":
So, The length of the side is given by
Hence, Second Option is correct.
(-6, -2)/(-7, -2)
y-y/x-x
(-2- -6)/(-2- -7)
(-2+6)/(-2+7)
4/5 = slope
Answer:Thang will pay $300 as interest
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 3 years
P = $2000
R = 5%
Therefore
I = (2000 × 5 × 3)/100
I = 30000/100
I = $300
Angle 1. Because angle 4 and 1 are vertical angles and vertical angles are congruent.
