50

Пошаговое объяснение:

х= -8. Подставляем -8 в уравнение вместо х.

18 * |-8+6| + |-8-6| = 18 * |-2| + |-14| = 18*2+14 = 36+14 = 50

. Read the interview with a successful teenager who has become a big wakeboarding star and match the questions and the answers.
• There is one extra question.

A What is wakeboarding? F How did you get into it?
B Do you spend lots of time on the water? G Do you have to wear any special clothes?
C Bet your mates are proud! H What's your ambition?
D What do your parents think of your hobby? I How good are you then?
E Any cringey moments? J What about schoolwork?

Sporty superstar
Example: A What is wakeboarding?
It's like waterskating, except both your feet are attached to one board.
Then you get pulled along behind a motor boat.
1. _______________________________________
My family were looking for a hobby to do together. We started wakeboarding and I loved it. A friend suggested I should train for competitions as he thought I was good.
2. _______________________________________
I'd love to do it every day, but I train mainly at the weekend. Then I do five 20-minute sessions a day. I warm up and then I do 180-degree jumps.
3. _______________________________________
I do my homework in the week and concentrate on wakeboarding at the weekend. I manage to fit it in because I really enjoy it.
4. _______________________________________
I came fourth in a national wakeboarding tour competition called "The White Stuff” recently. I was against women a lot older then me because there were no junior classes. Dad was so nervous, he was biting his nails all day.
5. _______________________________________
Yes, but I think they're quite jealous, too. They think I'm showing off, but I'm good at it! My teachers are great — they give me lots of encouragement.
6. _______________________________________
Lots! I'm always falling down and doing "face plants" on the water. That's like a belly-flop, but you land on your face, it gives you a bit of a headache but you get used to it. I also swallow lots of water, which doesn't taste very nice.
7. _______________________________________
I wear a dry suit, which doesn't let water in and a woolly jumper to keep me warm. It gets so cold in winter — nearly freezing. I might look silly but who cares?
8. _______________________________________
To become the best in Europe. Also, I'm hoping to be able to do an "invert" soon, which is an upside-down somersault. I want to train in Florida again, too. I went last year for two weeks of intensive training and loved it.
