Answer:
Perform the actual multiplication problem either by hand or with a calculator. In this example, students would multiply 21 times 31 to get 651. Subtract the smaller number from the larger one to check for reasonableness. In this example, you would subtract 600 from 651 to get 51.

Answer:
3√2
Step-by-step explanation:
Given the following;
DB = 3
CD = 6,
Required
find AD.
using the similarity property of a triangle
DB/AD = AD/CD
3/AD = AD/6
3*6 = AD²
18 = AD²
AD = √18
AD= √9*√2
AD = 3√2
Hence the measure of AD is 3√2
Not enough information. The question doesn't say how much one quart of paint covers.
EDIT: here's the solution
we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. <span>so we subtract the area of the door from the area of the walls, so we have: 704-24=680. </span><span>Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. </span>
Answer:
What are the scores?
Step-by-step explanation:
They can’t be similar. Similar triangles have congruent corresponding angles, and two angles are given on each. Neither of those correspond to another on the opposite triangle. Basically, there’s no way to have three congruent angles, so they aren’t similar.
