X=0. Y=-2. There is only one x value for this question.
Answer:
x= 3, x=5 or x^2 + 8x + 15
Step-by-step explanation:
(x+3)(x+5)
(x*x)(x*5)(3*x)(3*5)
x^2 + 5x + 3x + 15
x^2 + 8x + 15
x+3 = 0 x+5 = 0
-3 -3 -5 -5
x= -3 x= -5
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
Answer:
Step-by-step explanation:
No you are correct. That's the correct end result. Technically you should start with
Area = s^2
Area = 64 ft^2
s^2 = 64
sqrt(s^2) = sqrt(64)
s = 8
s = - 8 has no meaning.
Your way is fine.
