MATHEMATICS MIDDLE SCHOOL

(5p+11)-(3p+7)=-4 ^^please show the work with the answer. also, if you could do the check, that would be very helpful. thank you soooo much :))

Answers

Answer 1
Answer: Step  1  :Pulling out like terms :

 1.1     Pull out like factors :

   2p + 8  =   2 • (p + 4) 

Equation at the end of step  1  : Step  2  :Equations which are never true :

 2.1      Solve :    2   =  0

This equation has no solution.
 A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 2.2      Solve  :    p+4 = 0 

 Subtract  4  from both sides of the equation : 
                      p = -4

One solution was found :                   p = -4

After being rearranged and simplified, which two of the following equations could be solved using the quadratic formula? A) 5x^3+2x-4=2x^2 B) x^2-6x-7=2x^2 C) 2x^2-3x+10=2x^2+21 D) 5x^2-3x+10=2x^2

Answers

Answer:

B & D

Step-by-step explanation:

The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified

The two equations after simplifying will give quadratic equations are:-

x ²-6x-7=2x² and 5x²-3x+10=2x².

What is a quadratic equation?

The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.

Solving for the quadratic equation:-

Option B:-

x ² -   6x   -   7  =   2x²

- 2x²   +   x ² -   6x   -   7  =  0

x ²  +  6x  +  7  =  0

Option D:-

5x²   -   3x   +   10  =    2x².

5x²  -  2x². -   3x   +   10  =   0

3x²  -   3x  +  10  =  0

Therefore two equations after simplifying will give quadratic equations are- x ²-6x-7=2x² and 5x²-3x+10=2x².

If 300% of 0.18 is equivalent to 20% of b, then b is equivalent to what number?

Answers

B is equivalent to 270.

What is pencentage?

The calculation of per cent i.e., per 100 is known as percentage.

How to calculate percentage?

Here, 300% of 0.18 is equivalent to 20% of b

or, 300%*0.18=20%*b

or,54=b/5

or, b=270
