Use a protractor to measure the degrees of the angles. Then, join them together.
(2j+7)(2j−7)
=(2j+7)(2j+−7)
=(2j)(2j)+(2j)(−7)+(7)(2j)+(7)(−7)
=4j2−14j+14j−49
=4j2−49
Answer:
8 and 10
Step-by-step explanation:
the ratio of the two numbers is 4:5
So let's take 4 and 5 as our number, we find out that their LCM is 20.
The next pair would be 8 and 10. Their LCM is 40 , so they are the numbers.
