Answer:
The factors are 0 and -3
Step-by-step explanation:
In order to find the factors of this equation, you would have to set each term 6x and (x + 3), equal to 0 separately.
6x = 0
x = 0
x + 3 = 0
x = -3
Answer:
Step-by-step explanation:
5(x+7) + 2(y-1)
here x=7 and y=2
so 5(7+7)+2(2-1)= 5*14+ 2*1
70+2=72
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1
Consider the left side
2cos²A - 1 ← replace 1 by sin²A + cos²A
= 2cos²A - ( sin²A + cos²A)
= 2cos²A - sin²A - cos²A
= cos²A - sin²A = right side ⇒ verified
Answer:
I= 84
Step-by-step explanation:
for
since D is the rectangle such that 0<x<3 , 0<y<3
