Answer:
√2 and √5 and their difference are all real numbers
Step-by-step explanation:
In looks like you want to know if the difference ...
is a real number.
The square root of a non-negative number is a real number. The sum or difference of real numbers is a real number.
The sum you have indicated is a real number, approximately ...
√2 -√5 ≈ 1.4142 -2.2361 ≈ -0.8219
Its really easy. just look at the middle line. now the sides are only the answers including the square roots. so the line in the middle represents 12. The answer is 12
Find the probability of getting a sum of 35 while rolling 10 number cubes.
we know that
posiible outcomes=6x6x6x6x6x6x6x6x6x6=6^10=60,466,176
To find out the number 35
35=8(4)+2+1
35=6(5)+2+ 1+1+1
35=5(5)+5(2)
35=4(5)+4(3)+2+1
35=3(5)+4(4)+2+1+1
35=5(6)+5(1)
35=4(6)+5(2)+1
35=3(6)+2(5)+2(2)+3(1)
35=2(6)+5+
Answer:
x=75
Step-by-step explanation:
∆FSJ~∆DYJ
so the sides are proportional
SJ/YJ=FJ/DJ
(63+42)/42=(x+50)/50
105/42 ×50=x+50
125-50=x
x=75
Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
