Multiply (x+3)(3x+8) x times 3x =3x^2 then multiply x times 8 = 8x
keep multiplying 3 times 3x =9x then 3 times 8=24
then multiply the -3x(x+3)= -3x^2-9x
your hole expression will look like this 3x^2+8x+9x+ 24-3x^2-9x
if you need to simplify you can do by adding or subtracting them.
for example you can add 8x+9x= 17x
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
Final answer: D
Answer:
<h3>
x = 27°</h3>
Step-by-step explanation:
2x + 2x + 72° = 180°
4x = 108°
x = 27°
Answer:
Triangles
Step-by-step explanation:
- Angle b
- Triangle BED
- Triangle ABC
Answer:
Well technically its inf due to the arrow, there are no points showing where to start from and where to end
the way you do it it you just count the amount of units it goes up, in this case for every square its going up 5 units, once you get that number you put that on top of your fraction, then you go over on the x axis till you hit your line (x axis is going by 10 every time). This would be your number on the bottom of the fraction.
Ill do what I can see here
