Answer:
a)13x+3
b) -3x-13
c)4x^2-24
d)-3x^2 +3x
Step-by-step explanation:
a) combine like terms
5x-3+8x+6 so combine the -3 and +6 and 5x and 8x
So 13x+3
b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.
2x -5 - 5x -8
So -3x-13
c) Distribute the four to everything in the brackets.
4(x^2-6) becomes 4x^2-24
d) Distribute:
-3x (x-1) becomes -3x^2 +3x
42 times 2 equals 84 degrees
Answer:
The largest integer is 31.
Step-by-step explanation:
Hi there!
Let <em>k</em> be equal to the smallest of the integers.
Let (<em>k</em>+2) be the next odd integer.
Let (<em>k</em>+4) be the final odd integer.
We're given that the sum of these three integers is 87. Construct an equation:
Combine like terms:
Therefore, the smallest integer is 27. Because the largest integer is k+4, the largest integer is therefore 31.
I hope this helps!
Answer:
53 degrees
Step-by-step explanation:
