Answer:
C. -7x^2 - 28
Step-by-step explanation:
Firstly simplify the bracket before doing anything;
4x(3x - 7) = 12x^2 - 28x
then go back to the question and substitute the expression(12x^2 - 28x) on the bracket and then work out the question;
12x^2 - 28x -19x^2...then group the values with the same exponent of x,
(12x^2 - 19x^2) - 28x
; -7x^2 - 28x
Answer:
total number of students is 25
AIZA AND GLAIZA came 60% of the 25 students that is 15th position
A) therefore students which came below them were= 10
B) Students who has scored greater than them were=> 15-2=13 (as they niether got less than 12 nor more than 12.)
Answer:
4/8
Step-by-step explanation:
Note:
sin(-θ) = -sinθ
sin(-15°) = -sin15° Use a calculator
sin(-15°) = -sin15° = -0.2588
sin(-15°) = -0.2588
