A.) is the correct answer.
In this expression, solve the multiplication in the parenthesis.
-5×p×4×z×6×u
since multiplication is commutative,
-5×p×4×z×6×u=-5×4×6×p×z×u= -120pzu
Now multiply this by 3.
(-5p4z6u)3 = (-120pzu)3 = -360pzu
Center of rhombus bisects 90°.
Sum of angles in triangle = 180°
x + x + 14 + 90 = 180
2x + 104 = 180
2 (x + 52) = 180
x = (180 ÷ 2) - 52
x = 90 - 52
x = 38°
4b²+20b+25=0
Divide everything by 4
b²+5b+ 6.25=0
use the quadratic formula
x= (-b+ or - √b²-4ac) /2a
x= (-5 + or - √5²-4*1*6.25) /2(1)
x= -5/2 so
in this case, b= -5/2
