A rectangle's length is 6 units greater than its width. write an equation expressing the rectangle's area, a, as a function of w

vladimir1956 [14]

Let the width be w

Width = w
Length = w + 6
Area = a

a = w(w + 6)
a = w² + 6w

Answer: a = w² + 6w

The center of a circle is at (2, -5) and it's radius is 12. What is the equation of the circle?

Svetach [21]

The equation for a circle is (x-h)^2 +(y-k)^2=r^2
You just have to plug in your coordinates h is the x and k is the y.
The r is radius squared.
so, (x-2)^2+(y-(-5)^2=144
You have to be careful of those tricky negative values. When you distribute the y-(-5) it turns into y+5.
So your answer is D.

Determine the value of x for the following isosceles triangle.

andrew11 [14]

Given :

▪︎This triangle is an isosceles triangle.

▪︎Measure of one of its legs = 6 inches

▪︎Measure of its equivalent leg $= \tt \frac{x}{9}$ inches

▪︎Measure of its base $= \tt \frac{5}{2}$ inches

Which means :

$=\tt 6 = \frac{x}{9}$

$=\tt \frac{6}{1} = \frac{x}{9}$

$=\tt 6 \times 9 = x \times 1$

$\hookrightarrow\color{plum}\tt 54 = x$

Let us check whether or not we have found out the correct value of x by placing 54 in the place of x :

$=\tt 6 = \frac{54}{9}$

$= \tt6 = 6$

Since the Left Hand Side of the equation is equivalent to the Right Hand Side of the equation, we can conclude that we have found out the correct value of x.

▪︎Therefore, the value of <u>x = 54</u>
