Answer: $w^{2} + 13w + 36 = (w + 4)(w + 9)$

Step-by-step explanation:

$w^{2} + 13w + 36 = (w + 4)(w + ?)$

w (w + ?) +4 (w + ?)

w² + ?w + 4w + ?

4w + ?w = 13w

Subtract both sides by 4w

?w = 9w

? = 9

4 (?) = 36

Divide both sides by 4

? = 9

$w^{2} + 13w + 36 = (w + 4)(w + 9)$

Answer:

$s = 54m +160$

Step-by-step explanation:

Given: The attachment

Required: Determine the equation

We start by picking any two equivalent points on the table:

$(m_1,s_1) = (2,268)$

$(m_2,s_2) = (4,376)$

Next, we determine the slope, M:

$M = \frac{s_2 - s_1}{m_2 - m_1}$

$M = \frac{376 - 268}{4-2}$

$M = \frac{108}{2}$

$M = 54$

The equation is then calculated as:

$s - s_1 = M(m - m_1)$

Where:

$M = 54$

$(m_1,s_1) = (2,268)$

So, we have:

$s - 268 = 54(m - 2)$

Open bracket

$s - 268 = 54m - 108$

Collect like terms

$s = 54m - 108 + 268$

$s = 54m +160$

Hence, the equation is: $s = 54m +160$

The ac is a leg of the right triangle <br> True <br> False

Vinil7 [7]

Answer:

False

Step-by-step:

The hypotenuse of the triangle is the side opposite to the right angle. The legs are the other two sides of the triangle. Since AC is on the opposite side of the right angle, it is the hypotenuse and therefore not a leg. Hope this helps!
