Answer: A, C, D
If you try plugging in a few different numbers into these equations, you will get only 1 result.
:)
x=-2
3(x + 5) = 9
3x+15=9
3x=9-15
3x=-6
÷3 ÷3
x=-2
hope this helped ya have a good day bro cya)
<span>X+y=11
Xy=30
</span><span>
x=11-y
(</span>11-y)y=30
11y-y²=30
11y-y²-30=0
y²-11y+30=0
y²-5y-6y+30=0
y(y-5)-6(y-5)=0
(y-5)(y-6)=0
y-5=0
y=5
y-6=0
y=6
x=11-y
x=11-5=6
x=11-6=5
x=6 y=5
x=5 y=6
Answer:
Below.
Step-by-step explanation:
1. a^2 - b^2 = (a - b)(a + b)
a^2 and b^2 are 2 perfect squares and a^2 - b^2 are their difference.
2. The order of multiplication does not matter because in algebra multiplication is commutative ( meaning any order gives the same result).
Here, in the given figure. Angle y° forms vertical opposite angle pair with Angle 163°, therefore they have equal values.
that means ~
