Answer:

Step-by-step explanation:

Solve for p:

p - 7 = 3

Hint: | Isolate terms with p to the left hand side.

Add 7 to both sides:

p + (7 - 7) = 7 + 3

Hint: | Look for the difference of two identical terms.

7 - 7 = 0:

p = 3 + 7

Hint: | Evaluate 3 + 7.

3 + 7 = 10:

Answer: p = 10

Hey there!☺

$Explanation:$

Solve for p | $-7+p=3$

In step 1, we will simplify both sides of the equation:

$p-7=3$

In step 2, we will add 7 to both sides:

$p-7+7=3+7\\p=10$

p=10 is your answer.

Hope this helps!☺

Find the discriminant for the following equation 3x^2+4x=2

hichkok12 [17]

Answer:

The discriminant is 40

Step-by-step explanation:

First, rewrite the equation as $3x^2+4x-2=0$ so that the equation is in the form of $ax^2+bx+c=0$ . Thus, the discriminant is $b^2-4ac=(4)^2-4(3)(-2)=16+24=40$ . This tells us that since the discriminant is greater than 0, then there are 2 real solutions.
