Answer:
Due to there being no negatives in this equation, you can pretty much just eliminate the first 3 answers.
However in working out, here is what I did.
x^2 + x - 30 = 12 (+30)
= x^2 + x = 42
Then you can conclude that the answer is D, due to 6 x 6 = 36, plus 7 equaling 42.
Answer:
D) 35.6
Step-by-step explanation:
Use pythagorean theorem
22^2 + 28^2 = 1268
Take square root of 1268, which equals to 35.60898763.
10 x 7 = 70
1 x 7 = 7
9 x 7 = 70 - 7
9 x 7 = 63
Answer:The number of angles & sides is always the same.
Step-by-step explanation:
Answer:
38-15c-4
Step-by-step explanation:
38-x=12c+4+3c
38-x=15c+4
x=38-15c-4
