Answer:
So the expression in standard form will be 
Step-by-step explanation:
We have given expression 
We have to write this expression in standard form
For writing in standard form first we have to multiply the expression
So after multiplication number 
So the expression in standard form will be
The outlier is 27, which is significantly smaller than the rest of the numbers. It's gonna make the mean misleadingly small
Answer:
(x, y ) = (- 2, 3 )
Step-by-step explanation:
given the 2 equations
7x - 2y = - 20 → (1)
9x + 4y = - 6 → (2)
multiply (1) by 2 making the coefficients of y equal and opposite
14x - 4y = - 40 → (3)
add (2) and (3) term by term
(9x + 14x ) + (4y - 4y ) = (- 6 - 40 )
23x = - 46 ( divide both sides by 23 )
x = - 2
substitute x = - 2 into either (1) or (2) for y
(2) - 18 + 4y = - 6 ( add 18 to both sides )
4y = 12 ( divide both sides by 4 )
y = 3
solution is (- 2, 3 )
Answer:
8:1
Step-by-step explanation:
the actual table's height in inches is 4*12 = 48 inches.
48/6 = 8
so the ratio is 8:1.
That cant be a triangle because all the angles have to add up to 180
