<span>y=2x+3 (Total vacation time equals 2 days times x plus the 3 days he was given at the start.
Each year has 2 six-month periods. After 4.4 years Roberto will have worked 8.8 six-month periods. He will have been given vacation days for each of the 8 whole working periods he has completed.
x=8
y=2*8+3
y=19</span>
Binomial theory : ( a - b ) ^3 = a^3 - 3a^2b + 3ab^2 - b^3 ;
Then, ( 2y - 3x ) ^3 = 8y^3 - 36y^2x + 54yx^2 - 27x^3
Answer:
A = 45
B = 90
C = 45
Step-by-step explanation:
Isosceles triangles have two side that are the same and two angles that are the same. Since one angle, B, is a right angle, 90°, that means the other 2 angles, A & C, added together equal 90°.
Divide 90 by 2 and you 45° for both A and C.
