7 0

Answer:

(20+2)(10+9)

Step-by-step explanation:

The area model is written as (a+b)(c+d). To write a multiplication problem into an area model, split it into numbers which add to it. Multiples of 10 are most commonly used.

For example 22*19 becomes (20+2)(10+9).

When a figure is translated, reflected, or rotated, what's the same about the original igure and its image? What's different?
Liula [17]

Answer:

The image of a translation, reflection, or rotation is congruent to the original figure, and the image of a dilation is similar to the original figure. Two figures are similar when one can be obtained from the other by a sequence of translations, reflections, rotations, and dilations.

Compare the y-intercepts and rates of change of the following items.
kotykmax [81]

Answer:

D.   They have the same slope ( rate of change) and the same y-intercept.

Step-by-step explanation:

I  y = 1.2x + 0.4.

II  The slope is (10-4)/(8-3) = 6/5= 1.2.

Its equation is

y - 4 = (1.2)(x - 3)

y = 1.2x - 3.6 + 4

y = 1.2x + 0.4.
