Which properties were used to solve the following problem?

Stels [109]

Step-by-step explanation:

25(2x) + 25(3y)

25 · (2 · x) + 25 · (3 · y)

(25 · 2) · x + (25 · 3) · y Associative property (a · b) · c = a · (b · c)

(25 · 2)x + (25 · 3)y

(2 · 25)x + (3 · 25)y Commutative property a · b = b · a

A rectangle has a length that is 2 meters more than the width. The area of the rectangle is 288 square meters. Find the dimensio

Rufina [12.5K]

Answer:

L = 18 and w = 16

Step-by-step explanation:

The area of a rectangle is found by A = l*w. Since the length here is 2 more than the width or 2 + w and the width is w, substitute these values and A = 288 to solve for w.

$A = l*w\\288 = w(2+w)\\288 = w^2 + 2w$

To solve for w, move 288 to the other side by subtraction. Then factor and solve.

$w^2 + 2w - 288 = 0 \\(w +18)(w-16) = 0\\$

Set each factor equal to 0 and solve.

w - 16 = 0 so w = 16

w + 18 = 0 so w = -18

Since w is a side length and length/distance cannot be negative, then w = 16 is the width of the rectangle.

This means the length is 16 + 2 = 18.

Find the distance x rounded to the nearest tenth.

anyanavicka [17]

Answer:

$x=0.1 ~ft$

Step-by-step explanation:

$cot30=\frac{B}{H} =\frac{B}{H}$

$\frac{\sqrt{3} }{2} =\frac{B}{H}=H=\frac{16}{\sqrt{3} }$

$sin70=\frac{X}{H} =\frac{P}{H}$

$sin70=\frac{x}{\frac{16}{\sqrt{3} } }$

$x=\frac{\sqrt{3} }{16 ~sin70}$

$=0.1152$

$x=0.1$

Answer:

(2) 6x^2+40x +50

Step-by-step explanation:

(4x+10)*(2x+5) = 8x^2 +40+50

minus 2x^2

=6x^2 +40 +50
