The length of a rectangle is (5x − 1) cm and the width is (11 − 2x) cm. If the perimeter of the rectangle is 44 centimeters, wha
daser333 [38]

Answer:

57 cm²

Step-by-step explanation

<em>l = length</em>

<em>w = width</em>

<em>p = perimeter</em>

<em />

<em>(5x - 1) = length</em>

<em>(11 - 2x) = width</em>

<em>44 = perimeter</em>

<em />

<em>Formula for the perimeter of a rectangle:</em>

<em>l + l + w + w</em>

<em>2l + 2w = p</em>

<em />

<em>Substitute the variables for the length and width with the values given to you by the problem, then solve.</em>

<em></em>

<em>2(5x - 1) + 2(11 - 2x) = 44</em>

<em>(10x - 2) + (22 - 4x) = 44 (Distributive property)</em>

6x + 20 = 44

6x = 24

x = 4

<em>Plug x = 4 back into the length and width.</em>

Length = (5x - 1), (5(4) - 1), (19)

Width =  (11 - 2x), (11 - 2(4)), (3)

<em>Area for a rectangle: Length × Width = Area.</em>

<em>19 × 3 = 57 cm²</em>

<em>This is all in cm so answer with cm²</em>

Answer:

230 - 151 + 180 + (43 - 12) = 290

Step-by-step explanation:

Use PEMDAS.

Evaluate the expression in the parentheses:

230 - 151 + 180 + (43 - 12)

43 - 12 = 31

230 - 151 + 180 + 31

Add and Subtract From Left to Right:

230 - 151 + 180 + 31

79 + 180 + 31

259 + 31

290

<em>None of the given options are correct. </em>

The equation of a parabola is 1/32 (y−2)2=x−1 .
Andru [333]

The given equation of parabola is

\frac{1}{32} (y-2)^2 = x-1

Which can also be written as

x = \frac{1}{32} (y-2)^2 +1

Here vertex (h,k) is (1,2)

And value of a is

a = \frac{1}{32}

Formula of focus is

(h+ \frac{1}{4a} , k)

Substituting the values of h,k and a, we will get

(1+ \frac{1}{4*(1/32) } , 2} = (1+ 8,2) = (9,2)

Therefore the correct option is the last option .

a 55 ft long drainage pipe must be cut into two pieces before installation. one piece is two-thirds as long as the other. find t
Hunter-Best [27]

Answer:

33 feet

22 feet

Step-by-step explanation:

Let the longer piece be x

Therefore the shorter piece is (2/3)x

x + (2/3)x  = 55                  Combine the left 2 terms.

(3/3)x + (2/3)x = 55           Add  

(5/3)x = 55                        Multiply both sides by (3/5)

(3/5) * (5/3)x = (3/5)*55

x = 33

The larger piece is 33 feet

The smaller piece is (2/3) * 33 = 22 feet
