Any it's your choice. You can do -3x times -9x then -9x times -3x or -2y times 3y then 3y times -2y. Remember to multiply the number after = too. Nice handwriting btw
7. Answer: +4, x ≥ 16
<u>Step-by-step explanation:</u>
x - 4 ≥ 12
Add 4 to both sides (to isolate the variable):
x - 4 <u>+ 4</u> ≥ 12 <u>+ 4</u>
x ≥ 16
Graph has a closed dot with an arrow pointing to the right of 16.

9. Answer: x ≤ 9
<u>Step-by-step explanation:</u>
x - 20 ≤ -11
Add 20 to both sides of the equation:
x -20 +20 ≤ -11 +20
x ≤ 9
Graph has a closed dot with an arrow pointing to the left of 9.

Answer:
h=55.4 mm
Step-by-step explanation:
Area of a triangle = 
where b is base and h is height
now just plug and chug
227.14 = 8.2h/2
227.14=4.1h
h=227.14/4.1
h=55.4
check answer:
55.4 * 8.2 /2 = 227.14, as proven by my calculator
