12in * 14in / 2 + 18in * 14in / 2 = 210 in²

210in² * 3 = 630 in²

Answer:

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

Complete the expressions that would make them a perfect square trinomial.
kirza4 [7]

Answer:

a) 16

b) 100

c) 64

d) \frac{81}{4}[/tex]

Step-by-step explanation:

Perfect square trinomial:

A perfect square trinomial has the following format:

(x \pm a)^2 = x^2 \pm 2ax + a^2

a.

x² – 8x

x^2 - 8x = x^2 - 2ax

So 2a = 8, a = 4. Then

a^2 = 4^2 = 16

The perfect square trinomial is x^2 - 8x + 16

b. x2 + 20x +

2a = 20, so a = 10

a^2 = 10^2 = 100

The perfect square trinomial is x^2 + 20x + 100

C.

x² – 16x +

2a = -16, so a = -8.

a^2 = (-8)^2 = 64

The perfect square trinomial is x^2 - 16x + 64

d. x2 + 9x +

2a = 9, so a = \frac{9}{2}

a^2 = (\frac{9}{2})^2 = \frac{81}{4}

The perfect square trinomial is x^2 + 9x + \frac{81}{4}[/tex]

NEED RN, WORTH 50!<br> What is the value of x?
xxTIMURxx [149]

Answer:

x = 5

Step-by-step explanation:

<u>Step 1:  Make an equation</u>

<u />\frac{32}{40} = \frac{4}{x}

<u>Step 2:  Cross multiply</u>

<u />\frac{32}{40} = \frac{4}{x}

32 * x = 4 * 40

32x = 160

<u>Step 3:  Divide both sides by 32</u>

<u />32x / 32 = 160 / 32

x = 5

Answer:  x = 5
