Using the distributive property, a(b+ c) = ab + ac. In this case, b is 30, so the blank is 30.

<span>8×(30+2)=(8×_)+(8×2)

8 </span>× (32) = (8×_) + (16)
256 = (8×_) + 16
240 = 8×_

30 = _

7. Using the distance formula, calculate how far Hector threw the ball. (4 points: 2

iragen [17]

The required distance covered is 90 units

<h3>Distance formula</h3>

The formula for calculating the distance between two points is expressed as shown:

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The required coordinates missing are (0, 42.78) and (90.42.78). Substiute the coordinate into the formula:

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$D=\sqrt{(42.78-42.78)^2+(90-0)^2}\\D=\sqrt{(0^2+(90)^2}\\D = 90 units$

Hence the required distance covered is 90 units

Well we know these two angles are congruent, so we set their angles equal to each other.
5w - 69 = w + 3
4w = 72
w = 18
Now we plug w back into one of the equations, and then multiply whatever number we get by 2.
18 + 3 = 21
21 x 2 = 42
The measure of STU is 42°
