Answer:
Step-by-step explanation:
i think that the answer is a, because the def of natural numbers match's and there all integers.
X^2-y^2=55
this means that
(x+y)(x-y)=55
we know that x-y=11 so we can write
(x+y)(11)=55
x+y=55/11 we divide by 11 and we obtain
x+y=5
x-y=11 this means
x=y+11 we replace in the other equation (x+y=5)
y+11+y=5
2y=5-11
2y=-6
y=-3
and you find out that also
x=8
Answer:
The fully factored form is 3(x^2 - 7))
Step-by-step explanation:
The only thing you can do with this equation is take out a factor of 3. You cannot simplify the resulting parenthesis without using irrational numbers.

Answer:
34, 56 . . . . degrees
Step-by-step explanation:
Let x represent the smaller angle. Then x+22 is the larger. Complementary angles have a sum of 90°:
(x)° +(x +22)° = 90°
2x = 68
x = 34
x +22 = 56
The two angle measures are 34° and 56°.
