we have
(a+b)(3a-b)(2a+7b)
step 1
Solve
apply distributive property
(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2
step 2
Multiply (3a^2-4ab-b^2) by (2a+7b)
6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
answer is
<h2>6a^3+13a^2b-30ab^2-7b^3</h2>
Answer:
<u>Nature</u> : The phenomena of the physical world collectively, including plants, animals, the landscape, and other features and products of the earth, as opposed to humans or human creations. (according to Oxford Dictionary)
(0,-4) would map into itself because it doesn’t move.
Answer:
C
Step-by-step explanation:
Check the picture below.
we know B is the midpoint of AC, and we know ED is 4 units, since AD is a total of 8, then AE must also be 4 units, meaning point E is the midpoint of AD.
since E is the midpoint of AD and B is the midpoint of AC, then EB is the midsegment of the triangle, and is parallel to the base DC.
∡ABE = 60°
∡AEB = 90°
