The answer is 376$ because 47 x 8.00 = 376$
Answer: 11
Step-by-step explanation: write the equation.
2(x+4)=30
Divide by 2
x+4=15
Subtract 4
x=11
Answer:
An elevation of 40 meters below sea level
Step-by-step explanation:
When your below sea level you will be in a negative alt. When you are above you will be positive sea level.
Answer:
AC ≈ 7.8 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = A (- 4, - 4 ) and (x₂, y₂ ) = C (2, 1 )
AC = 
= 
= 
= 
= 
≈ 7.8 ( to 1 dec. place )
Answer:
-25 and -4
Step-by-step explanation:
to solve this, you need to use the sum product pattern. this means you're going to take the x factor, 29x and separate it into it's squares.
(x^2+25x)+(4x+100)
then you take out the common factor in each separated equation
x(x+25)+4(x+25)
you see that the items in the parentheses are the same, this means that this is one of the equations you will use when factoring. the rest of the equation that is left out (the common factors) is the other equation
(x+25)(x+4)
to get the zeroes, you set each equation equal to zero and solve
x+25=0 x+4=0
x= -25 x= -4
