Answer:
<h2>The answer is 32</h2>
Step-by-step explanation:
3( 2c + d) - 4( c - d) + d²
when c = 1 and d = 3
Substitute the values of c and d into the above expression and solve
We have
3 [ 2(1) + 3 ] - 4 ( 1 - 3) + 3²
<u>Solve the terms in the bracket first</u>
➢ 3( 2 + 3) - 4( - 2) + 9
➢ 3( 5) + 8 + 9
<u>Simplify</u>
➢ 15 + 8 + 9
➢ 15 + 17
We have the final answer as
<h3>32</h3>

Answer:
Step-by-step explanation:
The key to solving this question is to find the distance bwtween the two points given
distance=y2-y1/x2-x1
(2,4)(4,8)
2=x1,4=y1
4=x2
8=y2
8-4/4-2
4/2=2
The depth of the water is increasing by 2 ft each minute
22 - 1 = -3d
21= -3d
21/-3= d
-7 = d
Bring the 1 to the other side by doing the opposite sign, so subtract 1. Solve the left side.
Bring the 3 to the other side by doing the opposite sign, so divide 21 by -3.
End with D equaling -7
Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
The Hypotenuse-Leg theorem states that two <em>right</em> triangles are <em>congruent</em> if and only if their hypotenuses and any of their <em>corresponding</em> legs are <em>congruent</em>. That is to say:
, 

, 
If we know that
,
,
and
, then we have the following outcomes:


Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
