Answer: 
Step-by-step explanation:

88 can be rewritten as 8 x 10 and 8 can be rewritten as
making a 2 come out of the root.

10 can be rewritten as 2 x 5.

2*2 can also be rewritten as
making a 2 come out of the root.

We can't keep simplifying the root.
1/2×12m×18.2m=109.2m2
109.2m2÷21.8m÷1/2=10m(nearest whole number)
h=10m
Answer:
3 a : 2 b = 6 : 1
Step-by-step explanation:
<em>
=
</em>
<em>3 ( a + b) = 5 ( a - b)
</em>
<em>3 a + 3 b = 5 a - 5 b
</em>
<em>5 b + 3 b = 5 a - 3 a
</em>
<em>
8 b = 2 a
</em>
<em>
2 a = 8 b</em>
<em><u>a = 4 b</u></em>
<em>3 a = 3 × 4 b</em>
<em><u>3 a = 12 b</u></em>
<em>3 a: 2 b = 12 b : 2 b</em>
<em>3 a : 2 b = 6 : 1</em>
