Answer:
The first one is the answer
Answer:
6 and -4
Step-by-step explanation:
a + b = 2
a - b = 10
Solve:
from the first eq.
a = 2 - b
replacing this value in the second eq.
(2-b) - b = 10
2 - 2b = 10
-2b = 10 - 2
-2b = 8
b = 8/-2
b = -4
from the second eq.
a - b = 10
a - (-4) = 10
a + 4 = 10
a = 10 - 4
a = 6
Check:
from the first eq.
6 + (-4) = 2
6 - 4 = 2
Answer & Step-by-step explanation:
<em>(x² - 5x)(2x² + x - 3)</em>
Multiply each term from the first expression into the second expression.
<em>2x⁴ + x³ - 3x² - 10x³ - 5x² + 15x</em>
Combine like terms.
<em>2x⁴ - 9x³ - 8x² + 15x</em>
So, after you multiply the expressions, your answer will be 2x⁴-9x³-8x²+15x.
7:6
reverse the numbers when given a ratio similar to this one. 6x7=42 and 7x6=42 so x is 6 y is 7
