Answer:
x(x + 1)
Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)

What is the surface area if this sphere?
Answer:
The surface area of the sphere is approximately equal to 379.9 square centimetres.
Step-by-step explanation:
The surface are a of a sphere with respect to radius is 4πr². We're given the diameter, of 11 cm, so we know that the radius is 5.5 cm.
With that we can find the surface area:
[tex]a = 4\pi r^2\\a = 4\pi (5.5cm)^2\\a = 4\pi \times 30.25cm^2\\a = \pi \times 121cm^2\\a \approx 3.14 \times 121cm^2\\a \approx 379.9cm^2[/tex]

can you help me?????
Answer:
Step-by-step explanation:
I don't do this question the way it is outlined. My way is a bit shorter.
The general equation is y = mx + b
You want the slope to be - 1/5 which you just read from the given equation.
So, so far you have y = -1/5x + b
Now for the point which is (5,-4)
x = 5
y = - 4
-4 = -1/5 * 5 + b
-4 = -1 + b
b = -4 + 1
b = - 3
the equation is y = -1/5 x - 3
===========================
Now let's do it your way.
y - y1 = m(x - x1)
x1 = 5
y1 = - 4
m = - 1/5
y - - 4 = -1/5(x - 5
y + 4 = -1/5x + 1 Take 4 from both sides
y = -1/5 x + 1 - 4
y = -1/5 x - 3
