The exponent positive 4 means we move the decimal four spaces to the right.
The 2.7 becomes 27,000 after doing so
If the exponent was negative, then we would move the decimal point to the left.
Answer:
2x+5
x is the unknown number, you times it by 2 and add 5 becaseu it is 5 more than twice the number which is 2x

Answer:
She should aim 6 feet down the wall
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
x/4 = y/2 ⇒ x = 2y
You have other equation:
x+ y = 18
Substitute
2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit
x = 2(6) = 12
Then, she should aim 6 feet down the wall.
