Answer:
-20x+8
Step-by-step explanation:
Step 1: rearrange the equation
16x^2 - 3x^2 - 7x - 13x +8
Step 2: solve the equation
16x^2 - 3x^2 = 13x^2
-7x - 13x = -20x
(the +8 will stay the same)
so when we put it all together it gives us
13x^2 - 20x + 8
Answer:
G-7×17=119
Step-by-step explanation:
A prime number is a number which has only two factors, 1 and itself.
A composite number on the other hand is any number that has more than two factors.
In the options
In F-5×15=75, 15 can still be decomposed into 5X3
In H-9×19=171, 9 can still be decomposed into 3X3
In J-11×21=231, 21 can still be written as 7X3.
So option G is the only equation which could show Brodricks work.
