Answer:
-19/15 or -1 and 4/15
you can turn them into improper fractions then do the butterfly method
Answer:
24
Step-by-step explanation:
Use the triangle area formula: A=1/2 (base)(height)
Plug in what we know: 216=1/2(18)(h)
Solve for h: (1/2)(18)=9.
216/9=24.
So, h=24
To check, plug it into the formula: 1/2(18)(24)= 216
Answer:
2(x-11/4)^2 -9/8
Step-by-step explanation:
A. They are not similar because their corresponding angles are not congruent.
Their angles are not the same.
The 1st triangle is a scalene triangle (a triangle that has 3 unequal sides and angles)
The 2nd triangle is an isosceles triangle (a triangle that has 2 congruent/equal sides and 2 congruent angles)
Answer:
x = -2/3
Step-by-step explanation:
27 ^(x+2) = 81
Rewrite 27 as a power of 3
27 = 3^3
Rewrite 81 as a power of 3
3^4
3^3^(x+2) = 3^4
We know that a^b^c = a^(b*c)
3^3*(x+2) = 3^4
3^(3x+6) = 3^4
The bases are the same so the exponents are the same
3x+6 = 4
Subtract
6 from each side
3x+6-6 =4-6
3x = -2
Divide by 3
3x/3 =-2/3
x = -2/3
