(4) 64 tiles, (5) 
, (6) 
Step-by-step explanation:
Given data: Side length of square tile = 1 ft
(4) Side length of square pool = 8 ft
= 64
Hence 64 tiles needed for the border.
(5) Suppose number of square tiles be N and side of square tub is s ft.
So, N = 
So, the expression is .
(6) The equivalent expression is 
.
Answer:
y = - 
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x + ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= -
Using the point- slope form
with m = - and (x₁, y₁ ) = (- 2, 4) , then
y - 4 = - (x - (- 2) ) , that is
y - 4 = - (x + 2) ← distribute
y - 4 = - x - 3 ( add 4 to both sides )
y = - x + 1 ← in slope- intercept form
Answer:
50 is your answer
Step-by-step explanation:
Estimate by rounding both numbers to the nearest ten.
164 rounds to 160.
219 rounds to 220.
160+220=380
Final answer: 380
Answer: 11x^2
Step-by-step explanation:
I suppose that the options are:
a) 9/x
b) 11x^2
c) 20x^9-7x
d) 20x -14
First, a polynomial is something like:
aₙx^n + .... + a₂*x^2 + a₁*x^1 + a₀*x^0
Where n is the degree of the polynomial, the therms a are the coefficients, and aₙ is the leading coefficient.
Depending on the number of terms of the polynomial, it takes different names.
If we have only one term, it is called a monomial, if it has two terms, it is called a binomial, and so on.
So if we want to find a monomial, then we need to look at the options with only one term.
The options with only one term are options a and b.
But option a is a quotient (we have a negative power of x: 9/x = 9*x^-1)
So this is not a polynomial, then the correct option is option b.
