Answer:

The answers are as follows: 12 106 42

Step-by-step explanation:

Given: $ 18 - 4^2 + 5 \times 2 $  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate $ 18 - 4^2 $ separately and $ 5 \times 2 $ separately and add them. So we have $ 18 - 16 + 10 = 2 + 10 =12 $.

Now for the second question: $ 9^2 + 4 \times 7 - 3 $. we would get $ 81 + 28 - 3 = 106 $

Next, $ 5^2 - 4 + 7 \times 3 $. This could be written as:  $ 25 - 4 + 21 = 42 $. Hence the answers.

Geometry, please answer question ASAP
german

Answer:

B.

Step-by-step explanation:

The ratio of the lengths of the sides of a 30-60-90 triangle is

1 : sqrt(3) : 2

From the 1 and 2, we see that the hypotenuse must be twice the length of the short leg.

From the 1 and sqrt(3) we see that the long leg is sqrt(3) times the length of the short leg.

Now we check for these two ratios in each choice.

A.

1 is twice 1/2. Check

sqrt(3)/2 is sqrt(3) times 2. Check

B.

10 is twice 5, not twice 5/2. This does not check.

C.

2sqrt(2) is twice sqrt(2). Check

sqrt(6) is 2sqrt(2) time sqrt(3). Check

D.

6 is twice 3. Check

3sqrt(3) is sqrt(3) times 3. Check

Answer: B.
