The maximum speed that a sailboat can reach depends on the size of the boat. The graph
below shows the maximum speed, v, that a
sailboat can reach as a function of its length, l.
Complete the following sentences based on
the graph of the function.
The longer the sailboat is, the
slower
it can go.
For a boat to reach the speed of 10
kilometers per hour, it needs to be at least
5
feet long
The maximum speed that an 8-foot boat
can reach is
kilometers per hour.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
