Area = 32 units^2. Formula for a right angle triangle is Length x Width x 1/2. The biggest triangle is 4 x 10. Put that into the formula you get 4 x 10 x 1/2 which equals 20. Medium triangle is 2 x 6. In the formula it’s 2 x 6 x 1/2 = 6. Small triangle is 2 x 2. In the formula it’s 2 x 2 x 1/2 = 2. And the small square is 2 x 2 which you multiply normally to equal 4. Now add them all up to get 32 units^2
<u>Answer:</u>
2(-5 - 7j) = -10 - 14j
<u>Step-by-step explanation:</u>
Using the distributive property means that we have to multiply both -5 and -7j by 2:
2(-5 - 7j)
⇒ 2 × -5 + 2 × -7j
⇒ -10 - 14j
Here a tip : if the top number is less then half of the bottom number, then it is less then 1/2.
less then 1/2 : 1/4, 1/5, 2/12
to be greater then 1, the top number must be bigger then the bottom number
greater then 1 : 6/5, 14/8, 11/10
