The expansion is:
(6m+7)(6m+7)=6m(6m+7)+7(6m+7)=36m^2+42m+42m+49=
36m^2+84m+49
<u>Answer:</u>
See below.
<u>Step-by-step explanation:</u>
<u>Given</u> :
- AB = DE
- AC = DF
- BC = EF
<u>Solving</u> :
- As the three sides of both triangles are equal, the triangles are <u>congruent</u> by SSS congruence
Answer:
Option A, 50 degrees
Step-by-step explanation:
<u>Step 1: Estimate this angle</u>
<em>Option A, works because looks about the size of 50 degrees</em>
Option B, doesn't work because it is not more than a right angle.
Option C, doesn't work because it is not an obtuse angle.
Option D, doesn't work because there is no way it is 15.
Answer: Option A, 50 degrees
Answer:
D
Step-by-step explanation:
Put m+2 in place of 'x'
(m+2)^2 + 1 <======expand
m^2 + 4m + 4 + 1 =
m^2 + 4m + 5
