Answer:

Width = 15 ft

Step-by-step explanation:

Given formula,

→ A = L × W

Let us assume that,

→ Length = 4x

→ Width = x

→ Area = 900 ft²

Then the value of width will be,

→ A = L × W

→ 900 = 4x × x

→ 4x² = 900

→ x² = 900/4

→ x = √225

→ [ x = 15 ft ]

Hence, the value of width is 15 ft.

How to solve for x 15 + 8x = 45 + 6x
Reil [10]

Answer:

15

Step-by-step explanation:

Let's solve your equation step-by-step.

15+8x=45+6x

Step 1: Simplify both sides of the equation.

8x+15=6x+45

Step 2: Subtract 6x from both sides.

8x+15−6x=6x+45−6x

2x+15=45

Step 3: Subtract 15 from both sides.

2x+15−15=45−15

2x=30

Step 4: Divide both sides by 2.

2x

2

=

30

2

x=15

Answer:

x=15

Plz help me i need it
Mila [183]

Answer:   4

<u>Step-by-step explanation:</u>

f(x) = 4x³ - x² + 1        g(x) = x - 1

                                 g(2) = (2) - 1

                                        = 1

f(1) = 4(1)³ - (1)² + 1

     =  4   -   1   + 1

<h2>      = 4</h2>

Cosec^2θ-1/cosec^2θ=cos^2θ​
denis-greek [22]

cosec(2t)=1/sin(2t) ==> 1/(2×cos(t)×sin(t))

cos(2t)= 1-2sin²t

or 2cos²t-1

or cos²t - sin²t

after we knew this informations we have to write it in the question

1/2×sint×cost-1/1/2×sint×cost=cos2t

-2×sint×cost+1/2sint×cost/1/2sint×cost=cos2t

the 2sint×cost will gone

-2×sint×cost+1=cos2t

lets take cos2t =1-2sin²t

-2×sint×cost+1=1-2sin²t

-2sint×cost=-2sin²t

cost=sint

that means the t is equal to 45 because sin45 and cos45 equal to √2/2

hopefully i didn't waste your time by reading and not understanding my English is not that good sorry
