I’m pretty sure it’s 6.4^4 • b^3
Answer:
x=

√69
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
x2−7x−5=5−5
x2−7x−5=0
Step 2: Use quadratic formula with a=1, b=-7, c=-5.
x=
−b±√b2−4ac
2a
x=
−(−7)±√(−7)2−4(1)(−5)
2(1)
x=

Step-by-step explanation:
<u>Right Triangles</u>
Right triangles have one of its interior angles with a measure of 90°.
In right triangles the Pythagora's Theorem is satisfied.
Being c the longest side (hypotenuse), a and b the shorter sides (the legs), then:

We have modified the image to include some known data. Both triangles are congruent since they share one side, have a right angle, and have the same base length.
This means the value of x can be calculated as the hypotenuse of the triangle 3-6-x:
