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
This is a division problem.
Divide 349.65 by 7
This is 49.95
Answer is $49.95
To check multiply 49.95 x 7= 349.65
Answer:
Step-by-step explanation:
3-x-3x=5
first combine like terms
3-4x=5
-4x=2
divide each side by -4
x=2/-4 or -1/2 or -0.5

Answer:
x=3
y=-1
Step-by-step explanation:
x=4+y
by substitution it in equation 1
weget
(4+y)+y=2
4+2y=2
y=-1
x=3
