Answer/explanation
4(3x+5)=-4
You will distribute the four to every term in the parenthesis,
12x+20=-4
Then you will combine like terms
12x+20=-4
-20 -20
12x=-24
Then you will divide 12 to isolate x

Obviously, -24 cancels out and you would get x=-2
Answer:
1024
Step-by-step explanation:
16x2=32
32x2=64
64x2=128
128x2=256
256x2=512
512x2=1024
x= previous term multiplied by 2
hopefully this helps :)
Answer:
32 +x+x=180(Sum of angles of a triangle)
32+2x=180
2x=180-32
2x=148
x=148/2
Therefore,X=74
X should be 300
15/x= 0.05
x= 15/0.05= 300
x=300
100 is 480% , times by 48
