Hello :
f(x) = (x-5)(x+2i)
= x² +2ix -5x-10i
f(x) = x² +(2i-5)x -10i
<span>coefficients : a =1 b = 2i-5 c =-10i</span>

Set up an equation to show (×+2)×5=y

Masteriza [31]

<span>5x+10 = y

Subtract 10 from both sides.

5x = y - 10

Divide both sides by 5.

x = 1/5y - 2

Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y

1 = y

amber owns a skateboard shop. amber wants to buy one thousand eight hundred forty six skateboard wheels. skateboard wheels sell

Sonbull [250]

Amber spends $5,307.25 and she can make 461 skateboards.
Divide 1846 by 2 and you get 923, you then multiply that by $5.75 and get $5,307.25.
Then, you'll divide 1,845 by 4 and get 461.5. (she can only make 461 full skateboards.)

Answer:

The next statements are are;

Statement ${}$ Reason

Segment $\overline {DC}$ ≅ Segment $\overline {AB}$ ${}$ CPCTC

$\overline {AD}$ ≅ $\overline {BC}$ and $\overline {DC}$ ≅ $\overline {AB}$ , therefore;

ABCD is a parallelogram ${}$ Parallelogram side theorem

Step-by-step explanation:

Statement ${}$ Reason

Segment $\overline {DC}$ ≅ Segment $\overline {AB}$ by Congruent Parts of Congruent Triangles are Congruent (CPCTC)

Given that $\overline {AD}$ ≅ $\overline {BC}$ and we have that $\overline {DC}$ ≅ $\overline {AB}$ , we get;

ABCD is a parallelogram ${}$ Parallelogram side theorem

The parallelogram side theorem states that a quadrilateral is a parallelogram if it has two pairs or sets of congruent opposite sides.
