The rectangle has an area of x^2-7x+10 square meters and a width of x−5 meters. What expression represents the length of the rec
Katyanochek1 [597]

Answer:

length = x - 2

Step-by-step explanation:

Area (A) of rectangle = lw ( l is the length and w the width )

A = x² - 7x + 10 = (x - 2)(x - 5) ← in factored form

l = \frac{A}{w} = \frac{(x-2)(x-5)}{x-5}

cancel the factor (x - 5) on the numerator/ denominator, hence

l = x - 2

Factor the binomial expansion. 81x4 – 648x3 + 1,944x2 – 2,592x + 1,296
scoray [572]

Answer:

648(x^{3} + 3x^{2} - 4x + 2)

Step-by-step explanation:

When factoring an expression like this, you need to divide all of the parts by a common number or variable. In this case, the only thing all of these numbers share is that they are divisible by 648. So, you would divide each number by 648 to simplify it, getting 1, 3, 4, and 2. Put these numbers in front of their respective variables, and put 648 outside of the parentheses to get the final answer.

Write an equation of the circle with center (6, 2) and radius 4.
luda_lava [24]

Answer:

(x-6)^2+(y-2)^2=16.

Step-by-step explanation:

(x-h)^2+(y-k)^2=r^2 is the equation for a circle with center (h,k) and radius r.

You are given center (6,2) and radius 4.

So we will replace h with 6 and k with 2 and r with 4.

This gives us:

(x-6)^2+(y-2)^2=4^2

Simplify:

(x-6)^2+(y-2)^2=16.
