Answer:

70.4metres

Step-by-step explanation:

Wheel Diameter = 0.7m

Wheel Radius; 0.7m / 2 = 0.35m

For one rotation of the wheel, the distance travelled = circumference of the wheel.

Circumference = 2 x pi x radius

= 2 × π × r

= 2 × π × 0.35

= 2.1991148575 m

Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions

Distance travelled with 32 full revolutions of the wheel = 32 x 2.1991148575 m =

Distance in meters = 70.37167544m

Approximately = 70.4m

Therefore, Elaine managed to cycle 70.4metres

Which strategy would you choose to expand (x+11)(2x+3) and write an equivalent expression
Vlad1618 [11]

Answer:

Step-by-step explanation:

Given the expression (x+11)(2x+3)

We want to expand it and write equivalent expression

Generally if we want to expand an expression we will take one of the expression in one bracket and multiply with the other bracket and then take the other expression and multiply it with the other

E.g, (a+b) × (c + d)

Then, we take a × (c+d) and also b × (c+d)

We can do it the other way round too and it will give the same results.

So, applying this to the given expression

(x+11)(2x+3)

x(2x+3) + 11(2x+3)

2x² + 3x + 22x + 33

2x² + 25x + 33

Then, the equivalent expression is 2x² + 25x + 33

(x + 11)(2x + 3) = 2x² + 25x + 33

Side length = √49 = 7 feet.

The perimeter of a square is 4s = 4*7 = 28 feet.
