hi
a ( b +c) = a*b +a*c
here a = -3
b = -4x
c = +5
so :
-3 ( -4x +5) = -3*-4x + -3* 5
= -12x + (-15)
= -12x -15
as I cannot add -12x and -15 ( they are two differents sort of figures )
so it's done
Answer:
-12/5×4/3
(because if anything is in divide if we have to convert it in multiply So we have to reciprocal it
therefore option A is correct -16/5
Answer:
180.48
Step-by-step explanation:
The area of a rectangle = bh
Area of a circle = π
Rectangle = 8 x 10 = 80
Circle = 3.14(
) = 200.96
But because it's a hlaf circle, divide the number by 2
100.48
Now add the numbers together
180.48
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
Answer:
6.2 is the difference
