Answer:
to verify this answer you need to substitute the answer you got for x
Step-by-step explanation:
7(3)-2=19
21-2=19
19=19
this means that you are correct

Answer:
Δs DEF and DRQ not similar ⇒ 2nd answer
Step-by-step explanation:
Let us revise the cases of similarity
- AAA similarity : two triangles are similar if all three angles in the first triangle equal the corresponding angle in the second triangle
- AA similarity : If two angles of one triangle are equal to the corresponding angles of the other triangle, then the two triangles are similar
- SSS similarity : If the corresponding sides of the two triangles are proportional, then the two triangles are similar
- SAS similarity : In two triangles, if two sets of corresponding sides are proportional and the included angles are equal then the two triangles are similar.
In triangles DEF and DRQ
∵ m∠EDF = m∠REQ ⇒ vertical opposite angles
∵ m∠E ≠ m∠R
∵ m∠F ≠ m∠Q
<em>Only one angle in the 1st triangle is equal to one angle in the other triangle, no other angles are equal, similarity needs at least two angles in one triangle equal to two angles in the other triangle </em>
∴ The two triangle are NOT similar by any case of similarity
∴ Δs DEF and DRQ not similar
Answer:n = 10 can make the inequality true
Step-by-step explanation:
The given inequality is
120 greater than or equal to 10n + 20. This means that the least value of n that would make the inequality true would be 10.
If we substitute n = 10 into the right hand side of the given inequality, it would result to 120.
So n = 10 can make the inequality true.
