Answer:
x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3
Step-by-step explanation:
Subtract 15 from both sides
8x=-15
Divide 8 on both sides
Now you get your answer
x=-15/8 or -1 7/15
OR
Combine like terms
9x+15=0
Subtract 15 from both sides
9x=-15
Divide 9 from both sides
x=-15/9
Simplify
x=-5/3 or -1 2/3
It should be 12.5 units^2 :)
ANY fractions bigger than 1/2 are closer to 1 than to 0.
The expression would be (70+5)
Answer:
1.1 : C - x^2 + x - 2
1.2 : A - 4a^2 - 6b^2 + 12
Step-by-step explanation:
When we have the expression p(x) - q(x), we can substitute those functions in:
(x^2 + 2x - 5) - (x - 3)
We can distribute:
x^2 + 2x - 5 - x + 3
and then combine like terms(2x & -x, -5 & 3)
x^2 + x - 2
This is the same as C.
We can start by distributing:
a^2 - 2b^2 + 3 - 4b^2 + 5 + 3a^2 + 4
Now, we can combine all the a^2 terms(a^2 & 3a^2):
4a^2 - 2b^2 + 3 - 4b^2 + 5 + 4
Then, we can combine the b^2 terms(-2b^2 & -4b^2):
4a^2 - 6b^2 + 3 + 4 + 5
and lastly, all the constants:
4a^2 - 6b^2 + 12
This aligns with option A
