c. (x + 5)(x - 7) use the FOIL method.
x² + 5x - 7x - 35
x² + (5x - 7x) - 35 collect like terms.
x² - 2x - 35
hope that helps, God bless!
When written in scientific notation, 3,900 = 3.9 x 10^3
Answer:
there is nothing
Step-by-step explanation:
we know that
A number is an inequality solution if the number satisfies the inequality
<u>Part 1)</u>
rewrite the inequality
The answer Part 1) is the option D
Because satisfies the inequality
-----> is true
<u>Part 2)</u>
The answer Part 2) is the option A
Because satisfies the inequality
-----> is true
<u>Part 3)</u>
we're going to verify every case
<u>case A)</u> For
substitute the value of x in the inequality
------> is true
therefore
The number is a solution
<u>case B)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case C)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case D)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
therefore
The answer Part 3) is the option A
Answer:
Yes, 3/7 is bigger than 2/5
Step-by-step explanation:
First, put the fraction side by side
Multiply diagonally. So multiply 3 × 5 and 2 × 7
3 × 5 = 15
2 × 7 = 14
15 >14
