6 and 10 are part of the 2 table so you would have 2(3x-5) thats the farthest we can factor it down :)

The answer is b

2/5 times 2/5 is equal to 4/25

these events don’t have relation so they are independent

My 11 year old came home with this math problem. 1.5 [ 3( 14.5 +7 ) -3 ] - 7.4

nikitadnepr [17]

The solution of given problem 1.5 [ 3( 14.5 +7 ) -3 ] - 7.4 is 84.85

<em><u>Solution:</u></em>

Given problem is:

1.5 [ 3( 14.5 +7 ) -3 ] - 7.4

We have to use BODMAS rule to solve the problem

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right

Thus in the given problem, first we have to solve for brackets

Add 14.5 and 7 inside the brackets

$\rightarrow 1.5 [ 3( 14.5 +7 ) -3 ] - 7.4\\\\\rightarrow 1.5 [ 3(21.5) - 3 ] - 7.4$

Multiply 3 with 21.5

$\rightarrow 1.5[64.5-3] - 7.4$

Now again solve for brackets by subtracting 3 from 64.5

$\rightarrow 1.5 \times 61.5 - 7.4$

Now perform multiplication of 1.5 and 61.5

$\rightarrow 92.25 - 7.4$

Now perform subtraction

$\rightarrow 92.25 - 7.4 = 84.85$

Thus the solution of given problem is 84.85

Use triangle ABC below to answer the question that follows:

AnnyKZ [126]

Answer: Choice 1) The sum of the angles A and B are supplementary to angle C

Why is this the answer? Because we'll use facts 2 through 4 to help prove the triangles similar. If fact 2 is true, then fact 3 leads to helping set up the congruent corresponding angles (either A = D or C = E). Fact 4 is true because all angles are congruent to themselves, and this fact is the other angle pair we need to prove the triangles similar.

We don't use fact 1 even though it's a true statement. The fact that A+B+C = 180 isn't really useful to compare across two triangles.
