Answer:
we use distributive property.
Step-by-step explanation:
for example:
4(5x+7)=
4x5x=20x
4x7=28
so the answer is:
20x+28

Answer:
y =
x - 11
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (6, 10)
m =
=
=
, thus
y =
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, - 4) , then
- 4 = 7 + c ⇒ c = - 4 - 7 = - 11
y =
x - 11 ← equation of line
Answer:
The answer is 314cm²
the formula for the sphere area of a sphere is:
A= 4TT²
A = 4x3.14x5²
first solve for exponents
A = 4x 3.14x25
then multiply
A = 314cm²
