Answer:

Step-by-step explanation:

(2x - 3)^{2} = 4x - 6

Using FOIL, we can expand the polynomial on the left-hand side of the equation:

4x^{2} - 12x + 9 = 4x - 6

Next, let's move all of the terms to the left-hand side of the equation and combine like terms:

4x^{2} - 12x - 4x + 9 + 6 = 0

4x^{2} - 16x + 15 = 0

Now we can factor the quadratic:

(2x - 5)(2x - 3) = 0

This produces two equations to give us the two solutions:

The first solution:

2x - 5 = 0

2x = 5

x = \frac{5}{2}

and the second solution:

2x - 3 = 0

2x = 3

x = \frac{3}{2}

So the solutions to this problem are x = \frac{3}{2}, \frac{5}{2}

The degree of the polynomial f (x) is 3, and the degree of the polynomial g(x) is 4. Find the degree of the polynomial f (x) + g
Ratling [72]

Answer:

The degree would be 4

Step-by-step explanation:

When you add polynomials without multiplying bases, you cannot add or subtract the degree. So the highest degree would be 4 in this case.

The sides of a rectangle are 8cm and 6cm. What is the length of the diagonal. 12cm 10cm 9cm 7cm
tatiyna

Answer:

10 cm

Step-by-step explanation:

The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d

Using Pythagoras' identity in one of the right triangles, then

d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )

d = \sqrt{100} = 10 cm

In ΔJKL, k = 9.6 cm, l = 2.7 cm and ∠J=43°. Find ∠L, to the nearest 10th of a degree.
Bogdan [553]

Answer:

L = 10.64°

Step-by-step explanation:

From the given information:

In triangle JKL;

line k = 9.6 cm

line l = 2.7 cm; &

angle J = 43°

we are to find angle L = ???

We can use the sine rule to determine angle L:

i.e

\dfrac{j}{SIn \ J} = \dfrac{l}{ SIn \ L}

Using Pythagoras rule to find j

i,e

j² = k² + l²

j² = 9.6²+ 2.7²

j² = 92.16 + 7.29

j² = 99.45

j = \sqrt{99.45}

j = 9.97

∴

\dfrac{9.97}{Sin \ 43} = \dfrac{2.7}{ Sin \ L}

{9.97 \times    Sin (L ) = (2.7 \times Sin \ 43)

=  Sin \ L = \dfrac{ (2.7 \times Sin \ 43)}{9.97 } \\ \\ =  Sin \ L = \dfrac{ (2.7 \times 0.6819)}{9.97 }  \\ \\  = Sin \ L = 0.18466 \\ \\  L = Sin^{-1} (0.18466) \\ \\  L = 10.64 ^0
