Well, split it into 3 shapes
21 x 10 = 210
3 x 6 = 18
2 x 6 = 12
210 + 18 + 12 = 240 square cm
imahe for more context
plzzz give me brainliest
3x+40=100
subtract 40 from both sides
3x= 60
divide by 3
x=20
each Sweater cost 20
Answer:
Because they are parallel:
Angles 1,3,5 and 7=125
180-125=55
Angles 2,4, 6 and 8=55
Hope this helps!
3. x+100 = 90 alternate interior angles are equal
subtract 100 from each side
x+100 - 100 = 90-100
x = -10
4. 17x+1 = 120 alternate exterior angles are equal
subtract 1 from each side
17x+ 1 -1 = 120 -1
17x = 119
divide each side by 17
17x/17 = 119
x =7
multiply 5 and 2 then that with 23.
5x2=10 23x10=230
