Let's simplify step-by-step.
2x+x(x+6)
Distribute:
=2x+(x)(x)+(x)(6)
=2x+x2+6x

=2x+x2+6x
=(x2)+(2x+6x)
=x2+8x
Answer:
=x2+8x
FACTORED
Factor 2x+x(x+6)

Answer:
(x, y) = ( -4 , 4)
Step-by-step explanation:
STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4
STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4
STEP 3:substitute the given value of x into the equation so y = 4 would be
x = -3 x 4 + 8
STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
Answer:
Dimes = 8 and
Quarters = 12
Step-by-step explanation:
Total value = 380 cents
let dimes be x
quarters be 2x - 4
100 pennies = $1
1 dime = 10 pennies
1 quarter = 25 pennies
Therefore;
$ 3.78 = 378 pennies
10x+25(2x-4)=378
10x + 50 x - 100 = 378
60 x = 378 + 100
60 x = 478
x = 478/60
= 7.9667
≈ 8
Therefore;
Dimes = 8 and
Quarters = 12
