Answer:
15x5−x4−2x3+21x2+7x
Step-by-step explanation:
=(3x2+x)(5x3+−2x2+7)
=(3x2)(5x3)+(3x2)(−2x2)+(3x2)(7)+(x)(5x3)+(x)(−2x2)+(x)(7)
=15x5−6x4+21x2+5x4−2x3+7x
=15x5−x4−2x3+21x2+7x
Answer:
A = 30 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
A = 1/2 (12)*5
A = 30 ft^2
Answer:
The answer is A.
Step-by-step explanation:
This is quite the odd question to see on homework, but looking at it a certain way helps determine the answer. two fourths are shaded in, and so is one twelfth. Since the other five twelfths are blank, it can be interpreted that the model is showing us A. This can be checked on a scientific calculator.
.5 / (1/12) = 6
Therefore, A is correct.
