Answer:

Crescent = 3, drop = 6, heart = 3, square = 0

Step-by-step explanation:

Assign each symbol a variable and set up an equation

Crescent = a

Drop = b

Heart = c

Square = d

There’s a few different ones we can set up here

2b + d = b + 2a

2a + 3b + d = c + a + 2b

a + c = b

2b + d = b + 2a can be simplified to

b + d = 2a we can do something with this and a + c = b

a = b - c

d = 2a - b

c = b - a

b = a + c

If you work out this system of equation you get the answer at the top

Solve each equation 3x^2=80

Lapatulllka [165]

Answer:

$x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}$

$x = \frac{\pm4\sqrt{15}}{3}$

Step-by-step explanation:

Hello!

Use the quadratic formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

First, let's convert our equation to standard form of a Quadratic: ax² + bx + c = 0

3x² = 80

3x² - 80 = 0

Note, thats the value of b will be 0, as there is no "bx"

Now, solve:

$x = \frac{-(0) \pm \sqrt{(0)^2 - 4(3)(-80)}}{2(3)}$ Plug in values
$x = \frac{\pm\sqrt{960}}{6}$ Simplify the radical (Discriminant)
$x = \frac{\pm8\sqrt{15}}{6}$ Pull out perfect squares
$x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}$ Reduce factors

The solutions are $x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}$

Find the difference. (4x 2 - 6x + 8) - (3x 2 - 6x + 2) x2 + 6 7x2 - 12x - 6 x2 + 12x + 6 x2 - 12x - 6

Natasha_Volkova [10]

Answer:

x² + 6

Step-by-step explanation:

Given

(4x² - 6x + 8) - (3x² - 6x + 2) ← distribute by - 1

= 4x² - 6x + 8 - 3x² + 6x - 2 ← collect like terms

= x² + 6

Write an algebraic expression for the phrase the product of g and 4

Fudgin [204]

Product is the answer to a multiplication problem so we multiply g and 4.

4xg or 4(g). Or even simpler, you could do 4g.

hope it helps!
