You get 19.4 by multiplying 9.7 by 2 which = 19.4
Y +6 =(1/2)(x+4)
y +6 = 1/2 x +2
y=1/2 x - 4
or 1/2 x -y = 4
The equation will be 2x + 7 = 3x
subtract 2x from bothsides, you get 7 = x
so x is equal to 7
EDITED
sorry, i didnt read the sum part, so my answer is considered wrong ahaha
2(x+7) equals 3x
distribute, you get 2x+14=3x
then subtract 2x,
the answer for x is 14
Answer:
4x2−25
Step-by-step explanation:
(2x+5)(2x−5)
=(2x+5)(2x+−5)
=(2x)(2x)+(2x)(−5)+(5)(2x)+(5)(−5)
=4x2−10x+10x−25
4x2−25
