Answer:

$2{x}^{2} + 7x - 4$

Step-by-step explanation:

F [First terms] - Multiply the first terms in each set of parentheses FARTHEST TO THE LEFT

O [Outside terms] - Multiply the first term in the first set of parentheses FARTHEST TO THE LEFT by the last term in the second set of parentheses FARTHEST TO THE RIGHT

I [Inside terms] - Multiply the last term in the first set of parentheses FARTHEST TO THE RIGHT by the first term in the second set of parentheses FARTHEST TO THE LEFT

L [Last terms] - Multiply the last terms in each set of parentheses FARTHEST TO THE RIGHT

$(2x - 1)(x + 4) = 2{x}^{2} + 8x - x - 4 = 2{x}^{2} + 7x - 4$

What is the length of the side labeled x?

Answer:

AB = 42.15 units

Step-by-step explanation:

In triangle ABD,

By applying Cosine rule in this triangle,

cos(30)°= $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3} }{2}$ = $\frac{AD}{AB}$

$\frac{\sqrt{3}}{2}=\frac{AD}{47}$

AD = $\frac{47\sqrt{3}}{2}$

By applying tangent rule in ΔACD,

tan(44)° = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(44)° = $\frac{AD}{x}$

0.9657 = $\frac{\frac{47\sqrt{3}}{2}}{x}$

0.9657 = $\frac{47\sqrt{3}}{2x}$

x = $\frac{47\sqrt{3}}{2(0.9657)}$

x = 42.15

≈ 42.2 units

Answer:

1947 units^2

Step-by-step explanation:

you can split it up into different sections of rectangles.

the first one is 25x39= 975

The second section is the connector which you do

43-25=18

and you do 39-27=12 and then

you multiple 18x12 which equals 216

and the final section you do 24+12=36

and 36x21=756

and finally you add them all up to equal 1947 units^2
