Answer:
<H=<J
Step-by-step explanation:
Because they r corresponding angles so they are congruent. the rest of the statements r incorrect.
1. one line of symmetry
2. four lines of symmetry, also has rotational symmetry every 45°
3. no line of symmetry
4. two lines of symmetry
Square root of 9 is 3
Square root of 4 is 2
so 3/2
Make it negative and you got -3/2 for your answer.
Answer:
1680
Step-by-step explanation:
First do the prime factorization:
16=2x2x2x2
28=2x2x7
42=2x3x7
60=2x2x3x5
To find least common multiple (LCM), write down all prime factors of one of the number and multiply by factors from other numbers that was not in that number:
LCM=2x2x3x5x7x2x2=1680
Answer:
Step-by-step explanation:
surface area=2(l+w)×h+2×l×w
=2(14+5)×8+2×14×5
=2×19×8+140
=304+140
=444 inches²
