Answer: x = 16.75
Step-by-step explanation:
I'm not good at square roots but if you divide both sides by 2:
(2x – 9) • 2 / 2 = 49 / 2
simplify:
2x – 9 = 49/2
add 9 to both sides:
2x – 9 + 9 = 49/2 + 9
simplify:
2x = 67 / 2
divide both sides by 2:
2x ÷ 2 = 67/2 ÷ 2
simplify:
x = 67/4
Answer:
x = 16.75
Answer:
I have it in above pic hope it
The answer would be f(x)=9 because when you substitue the 3 in for 'x' you then square the 3.
Hope this helps!

Answer:
SSS
Step-by-step explanation:
Two triangles are said to be congruent if all their three sides are equal and all of their three angles are equal. There are 5 ways of determining congruent triangle which are:
- SSS (side, side, side): This is when the two triangles have all three sides equal to each other.
- SAS (side, angle, side): This is when the two triangles have 2 equal sides and one included angle of both triangles are equal.
- ASA (angle, side, angle): This is when the two triangles have 2 equal angles and one included side of both triangles are equal.
- AAS (angle, angle, side): This is when the two triangles have 2 equal angles and one non included side of both triangles are equal.
- HL (hypotenuse, leg): The hypotenuse is the longest leg of a right angled triangle. If two triangles have equal hypotenuse and one equal leg, they are congruent.
Triangle ABC and triangle BCD are congruent because:
AB = CD, AC = BD and both triangles share the same side BC. That is they have three equal sides (SSS)
