Answer from: Jolenesopalski

B. 5x6 + 3x4 + 6x3 + 5x2 − 2x

Step-by-step explanation:

A polynomial is in standard form when when its term of the highest degree is first, it's term of second highest is 2nd, and so on.

So, in our case, we can take a look at the exponents in each row.

A would be 6, 4, 5,2, and 1. That would not be correct since it is not from greatest to least. With the 6 being the highest and 5th being the 3rd highest.

C would be 0, 1, 2, 3, 4. That would not be correct since that is from least to greatest.

D. would be 1, 4, 6, 8 and 0. That again would not be correct since its numbers are going from least to greatest to least.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

Answer from: Quest

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
