Answer: x = 4; x = 5
Step-by-step explanation:
The directions specify to solve by factoring
x^2 - 9x + 20 = 0
To factor, find two numbers that add to -9 and multiply to 20
-5 and -4 work
-5 + (-4) = -9
-5 * -4 = 20
(x - 4)(x - 5) = 0
x = 4, x =5
Answer:
The third answer that is C is correct
The answer to this question is answer choice A.
We want three pairs of congruent sides, but we only have 2 pairs in the image. If AB is congruent to DE, we'll have 3 pairs of congruent sides and the triangle will be proven congruent by the SSS postulate.
Hope this helps! :)
a) 5x+30
you can factor out 5
5( x+6)
b) 2x^6 -12x^2
the GCF is 2x^2
2x^2 (x^4 -6)
(remember when factoring out the x^2 from x^6 you subtract the exponents
