If change from 313 to 533

a) median: It increased by 15

b) mean: It increased by 22

A=bh/2, Area=(base*height)/2, in this case:

A=11*13/2

A=71.5 in^2

**Answer:**

It doesn't make sense

**Step-by-step explanation:**

**Given**

**Statement: **.... at a speed of 35 miles .....

**Required**

Does it make sense?

In motion, speed is measured in km/h, m/s, miles per hour (depending on context) while distance is measured in km, m or miles.

However, the given statement mention the unit of speed to be miles which is incorrect.

Hence, we can conclude that the statement does not make sense.

A correct statement would be:** **<em>**I drove at a speed of 35 miles per hour .......**</em>

**Answer:**

x = (-9)

**Step-by-step explanation:**

From the diagram, we see that the triangle is an isosceles triangle. Since it is an isosceles triangle we know that the angles at the base of an isosceles triangle are equal to each other, so the angles that is not marked will be equal to m∠2. Since now we know that, we can make the following equation...

m∠2 + m∠2 + 84 = 180

Now we solve it and get...

2(m∠2) = 180 - 84

2(m∠2) = 96

m∠2 = 48

Now we substitute m∠2 with x + 57, and get...

m∠2 = 48

x + 57 = 48

x = 48 - 57

x = (-9)
