xy + | -49/1| (-1)

Let x=7 and y = 8

7*8 + | -49/1| (-1)

56 + | -49/1| (-1)

The absolute value of -49 is 49

56 +49 (-1)

Multiply

Answer:

Step-by-step explanation:

Step 1: Define

xy + |-49/1|(-1)

x = 7

y = 8

Step 2: Simplify

xy + |-49|(-1)

xy + 49(-1)

xy - 49

Step 3: Substitute and Evaluate

7(8) - 49

56 - 49

How do i solve this quadratic equation x²+6x+c

Anuta_ua [19.1K]

recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.

$\bf 6x=2\cdot \sqrt{x^2}\cdot \sqrt{c}\implies 6x=2\sqrt{x^2c}\implies 6x=2x\sqrt{c}\\\\\\\cfrac{6x}{2x}=\sqrt{c}\implies 3=\sqrt{c}\implies 3^2=c\implies 9=c$
