Answer:

When a dilation in the coordinate plane has the origin as the center of dilation, you can find points on the dilated image by multiplying the x- and y-coordinates of the original figure by the scale factor. For scale factor k, the algebraic representation of the dilation is (x, y) → (kx, ky)

Simplify the expression (4-5i)(2+6i)-(3-2i) show your work.

Anastaziya [24]

The simplification of the given expression $(4-5i)(2+6i)-(3-2i)$ , we get $-30i^2+16i+5$ .

Given expression is:

$(4-5i)(2+6i)-(3-2i)$

By applying the multiplication, we get

→ $(8-10i+24i-30i^2)-(3-2i)$

By multiplying the (-) sign into the bracket, we get

→ $8-10i+24i-30i^2-3+2i$

→ $5+16i-30i^2$

By arranging the terms, we get

→ $-30i^2+16i+5$

Thus the answer above is right.
