Answer:
x = 2
Step-by-step explanation:
DE is parallel to AC and intersects the other 2 sides, thus divides those 2 sides in proportion, that is
= ( cross- multiply )
6x = 4(x + 1) , that is
6x = 4x + 4 ( subtract 4x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
if there is more than 1 x u add the exes but you dont add the exes with the other numbers so in this case you would do 7 x 2/3 and you would leave the x alone
2x²-2x-12=0
x²-x-6=0
(x-3)(x+2)=0
x-3 =0, x+2=0
x(1)=3, and x(2)=-2
The solutions make the equation true, and the solutions give x-intercepts of the graph of the equation.
(-2, 0) and (3,0) are x -intercepts for the graph of y = 2x²-2x-12
Answer:
Yes, they will have the same density.
Step-by-step explanation:
Density has nothing to do with the size of an object.
'of' means multiply
1/4 of (1/4 times ) the opposite of (-) difference of 5 and a number (5-n) is lesss than 20 (<20)
1/4 times -(5-n)<20
multiply both sides by 1/4
-(5-n)<5
multiply both sides by -1 remember to flip sign
5-n>-5
add n
5>n-5
add 5
10>n
n<10
the number is any number less than 10
