X^2-7x-34=10<br><br> Please help me answer this question thank you
elena-s [515]

Answer: x = 4,11

Step-by-step explanation:

x^2 - 7x - 34 - 10 = 0

x^2 - 7x - 44 = 0

Factorise it

x^2 - 11x - 4x - 44 = 0

x ( x - 11 ) - 4 ( x - 11 ) = 0

(x-4)(x-11) = 0

x = 4,11

Please help me with this 20 points
JulsSmile [24]

Answer:

A  4/605

Step-by-step explanation:

mathematics = 11 letters

P(m) = number of m's/total = 2/11

we replace it so we have  mathematics = 11 letters

P(s) = number of s's/total = 1/11

not replacing it

we replace it so we have  mathematic = 10 letters

P(vowel) = number of vowel/total = 4/10 = 2/5

P(m, replace,s, no replace, vowel) = 2/11*  1/11 * 2/5 =  4/605
