What are the solutions to x2 + 8x + 7 =.b?

loris [4]

Answer:

x = 7 and x = -1

Step-by-step explanation:

First, we need to factor this quadratic.

To do this, start by finding all the factors of C.

7 x 1, -7 x -1

Now, we need to pick out the factors that add up to the b number, which is 8. That would be 7 and 1.

Now, we can use the numbers 7 and 1 to create two binomials.

( x + 7 ) ( x + 1 ) = 0

The last thing we need to do is to set those binomials to 0 and solve each of them individually.

x + 7 = 0

x = - 7

Solving the first binomial gives us our first solution, -7.

x + 1 = 0

x = -1

Solving the second one gives us our second solution, -1.

The solutions are -7 and -1.

Which statement is true about the polynomial 3x?y2 - 5xy2 - 3x²y2 + 2x2 after it has been fully simplified?

Sladkaya [172]

4 terms, degree of 2

The terms is the amount of “numbers” you have, which is 4
The degree is the highest power, which is x^2

The cost (in dollars) in making b bracelets is represented by 4+5b. The cost (in dollars) of making b necklaces is represented b

ddd [48]

Answer:

$P(b)=3b+2$

Step-by-step explanation:

The cost (in dollars) in making b bracelets is represented is

$B(b)=4+5b$

The cost (in dollars) of making b necklaces is

$N(b)=8b+6$

To find how much more it will cost to make b necklaces than b bracelets, we find the difference,

$P(b)=N(b)-B(b)$

$P(b)=8b+6-(4+5b)$

$P(b)=8b+6-4-5b$

$P(b)=3b+2$

This is a polynomial in descending powers of b, hence it is in standard form;
