Yes all your used tiles are correct.

Let's solve the equation too

2x+4=3x+(-1)
2x+4=3x-1
4+1=3x-2x
x=5

Find the area of the shaded region

olga2289 [7]

Answer:

27 in²

Step-by-step explanation:

area of triangle (whole) = 1/2 x base x height

= 1/2 x 10 x 6

= 30 in²

area of small triangle = 1/2 x base x height

= 1/2 x 3 x 2

= 3 in²

area of shaded region = 30 in² - 3 in²

= 27 in²

Find the value of c that makes the trinomial a perfect square. .<br> x² – 24x7c

sergey [27]

Answer:

144

Step-by-step explanation:

The equation to find c is:

$(\frac{b}{2} )^{2}$

So put -24 into b:

$(\frac{-24}{2} )^{2}$

Which simplifies to:

144

So if you want to test this:

x^2 - 24x + 144

(x-12)^2

Which model represents the factors of x2 9x 8? An algebra tile configuration. 7 tiles are in the Factor 1 spot: 1 is labeled x a

iren [92.7K]

The factors of an expression are the quotients of the expression

The model that represents the factors of $x^2 - 9x + 8$ is the product of x -1 and x - 8

<h3>How to determine the model</h3>

The expression is given as:

$x^2 - 9x + 8$

Expand the expression

$x^2 - 8x - x + 8$

Factorize the expression

$x(x - 8) - 1(x - 8)$

Factor out x - 8

$(x - 1)(x - 8)$

Hence, the model that represents the factors of $x^2 - 9x + 8$ is the product of x -1 and x - 8
