Answer:

#1. The correct answer is C. 5b²-b-2

#2. The correct answer is A. 4x-5

Step-by-step explanation:

#1. (5b²-3b+2)+(2b-4), combine like terms. ----->  5b² doesn't have any like terms, so you would move onto -3b and 2b, -3+2= -1 or in other words, just b. Now move onto +2 and -4, 2+-4= -2. So, your answer would be 5b²-b-2.

#2. (6x-3)-(2x-2), also, combine like terms here. -------> 6x has a like term in the other set of parenthesis, 2x. So, you would subtract 6-2= 4, and you would now have 4x. Same thing with -3 and -2. -3-2= -5. So, now your answer would be 4x-5.

<em>Hope this helped you understand!! (:</em>

What is the solution for -3(6x+5)-2(1-17x)=3(5+5x)
Novosadov [1.4K]

-3(6x+5)-2(1-17x)=3(5+5x)

Mutiply the first bracket by -3

(-3)(6x)= -18x

(-3)(5)= -15

Mutiply the second bracket by -2

(-2)(1)= -2

(-2)(-17x)= 34x

Mutiply the third bracket by 3

(3)(5)= 15

(3)(5x)= 15x

-18x-15-2+34x= 15+15x

-18x+34x-15-2= 15+15x

16x-17= 15+15x

move 15 to the other side

sign changes from +15 to -15

16x-17-15= 15-15+15x

16x-32= 15x

move -32 to the other side

sign changes from -32 to +32

16x-32+32=15x+32

16x= 15x+32

move 15x to the other side

sign changes from +15x to -15x

16x-15x=15x-15x+32

x= 32

Answer: x= 32

salantis [7]

Answer:

$966

Step-by-step explanation:

6/7 =  828/x

Write a proportion.

6x = 7(828) Use cross products.

6x = 5796 Multiply.

x = 966 Divide both sides by 6.

Paul's investment was $966.

Solve x^(2)+4x=4 for x by completing the square.
Mama L [17]

Answer:

x = 2 sqrt(2) - 2 or x = -2 - 2 sqrt(2)

Step-by-step explanation:

Solve for x:

x^2 + 4 x = 4

Add 4 to both sides:

x^2 + 4 x + 4 = 8

Write the left hand side as a square:

(x + 2)^2 = 8

Take the square root of both sides:

x + 2 = 2 sqrt(2) or x + 2 = -2 sqrt(2)

Subtract 2 from both sides:

x = 2 sqrt(2) - 2 or x + 2 = -2 sqrt(2)

Subtract 2 from both sides:

Answer: x = 2 sqrt(2) - 2 or x = -2 - 2 sqrt(2)
