Answer:
area of trapezium:
a+b divided by 2, times by the height.

28/2=14.
14*14=196.
area=196
Step-by-step explanation:
I can’t, sir! I cannot leave my post to help with your math problems, over!
1) 462/11= 42
42x7=294
2) 9.38/7= $1.34
3) 6/11= 0.54545454545455
4) 1/4= 0.25
2/9= 0.22222222222
3/10= 0.30
2/1= 2.00
1/5= 0.20
least to greatest- 1/5, 2/9, 1/4, 3/10, 2/1
5) 9/15= 0.6 > 60%
to turn into a percent, move 2 decimal places!
6) 10/4= 2.5
2.5x18= 45
7) 2/3= 0.66666666666
0.66666666666x7= 4.66666666667
Answer:
Infinite
Step-by-step explanation:
3(4x + 1) - 2
= 12x + 3 - 2 (Multiply the sum in the bracket by 3)
= 12x + 1 (Simplify)
This means that:
12x + 1 = 3(4x + 1) - 2
is the same as
12x + 1 = 12x + 1
Hence, anything that is used to substitute x is correct.
