Answer:
2 A. Exponential Expression.
2 B. Linear.
3 A. Linear.
3 B. Exponential Expression.
Just multiply 42 by 10 and that gives you 420 , so the real car has a length of 420cm or 4.2 metres :)
Here is the answer for a:
Answer:
x = -12.5
Step-by-step explanation:
Solve : -2x - 10 =15
-2x - 10 = 15
-2x = 15 + 10
-2x = 25
x = -25/2
x = -12.5
since this a 45 45 90 right triangle to get the side lengths you divide 2 times the square root of 2 and you get 2, since this has two congruent angles which makes it an Isosceles triangle. your a and b value are 2.
