5.Solve the quadratic equation.

Mathematics
1 answer:
Dafna1 [17]3 years ago
5 0

Answer:

x=5 twice

Step-by-step explanation:

x^2-10x+25=0

multiply the coefficient of x^2 and the last term

1X25=25

find two numbers you can multiply to get 25 and add to get -10

-5 + (-5)=-10 the middle term

replace -10x with -5x -5x and solve the equation

x^2-5x-5x+25=0

factorise by grouping

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

Either x-5=0,x=5 or x-5=0,x=5

Therefore x=5 twice.

lora16 [44]

(0.18 x 23.50) + 23.50

Step-by-step explanation:

First, find the percentage of 23.50 (equation in the parenthesis). 18% is equivalent to 0.18. Then, you add that to 23.50. That's the total amount Sam should pay. I hope this makes sense.
