Answer:

Factoring: (x+4)(x-6), x=-4 or x=6

Quadratic formula: x=6 or x=-4

Step-by-step explanation:

Factoring: (Reverse foil)

x^2-2x-24

because there are two - sign then we know it is

(x+ something)(x- something)

looking at the factors of 24 we can see that 6 and 4 are factors and 6-4=2 so

(x-6)(x+4)must be the factored form.

However the sign of x values in factored form changes when not in parenthesis so it would become x=6, and x=-4

Quadratic formula:

the quadratic formula is [-(b)+or-sqrt(b^2-4(a)(c)]/2(a)

in this case a=1, b=-2, c=-24 so it would be

[2+or-sqrt-2^2-4(1)(-24)]/2(1)=

[2+or-sqrt4-(-96)]/2=

[2+or-sqrt100]/2=

[2+or-10]/2=

1+or-5=

1+5 or 1-5

so x=6 or x=-4

If mRS=x then write an equation that could be used to solve for x and find the value of x
Fed [463]

Answer:

a) x = 30°

b) mRS = x = 30°

mST = 4x = 4(30°) = 120°

mTU = 4x = 4(30°) = 120°

mUR = 3x = 3(30°) = 90°

Question:

The complete question as found on Chegg website:

In the diagram below, secants PT and PU have been drawn from exterior point P such that the four arcs

intercepted have the following ratio of measurements:

mRS : mST :MTU : mUR=1:4:4:3

(a) If mRS = x, then write an equation that could be used to solve for x

and find the value of x.

(b) State the measure of each of the four arcs.

mRS =

mST =

MTU

MUR =

Step-by-step explanation:

Find attached the diagram related to the question

mRS : mST : mTU : mUR = 1:4:4:3

Since mRS = x

Writing the ratios of the measure of angle in terms of mRS:

mST = 4× mRS = 4×x = 4x

mTU = 4× mRS = 4×x = 4x

mUR= 3× mRS = 3×x = 3x

The sum of measure the 4 measures of arc = 360° (sum of angle in a circle)

mRS + mST + mTU + mUR = 360°

x + 4x + 4x + 3x = 360

12x = 360

x = 360/12

x = 30°

b) The measure of angle

mRS = x = 30°

mST = 4x = 4(30°) = 120°

mTU = 4x = 4(30°) = 120°

mUR = 3x = 3(30°) = 90°
