A, because 3x count as one, x count as one , and 4
The greatest common factor of 9, 18 and 21 is 3 so that is the number that we'll factor out
to do this divide all three numbers by 3 to get
3(3a-6b+7c)
I hope I've helped!
X= 31 because all the angles in a triangle equal 180 and 58+91 is 149, 180-149=31
Answer:
x=-4
Step-by-step explanation:
The angles have to equal eachother, so:
130=134+x
subract 134 from both sides
-4=x
Answer:2300 cm2
Step-by-step explanation:
First you want to divide 350 by 14. You get 25. Now multiply 25 x 26 and then divided by 2. Once you get that answer, multiply that 5 times since there is 5 triangles. Then, add that to the base area. Hopefully this is the right answer. let me know if it is.
