Answer:
a=-1
Step-by-step explanation:
we need to get a by itself
first combine like terms
12+16a=-4
now we need to get rid of the 12 so subtract it to other side
-16=16a
now divide 16 by -16 which gives you -1=a
Let's start by working out what percentage 38 / 55 is. To work this out, literally just do 38 ÷ 55, and then × 100. So Samantha got 69% (to the nearest percent).
To pass the test, you needed 70%. Therefore, Samantha failed as 38 ÷ 55 × 100 shows us that 38 marks is equivalent to 69%, which is not enough to pass.

Step-by-step explanation:
Volume of the prism is given by the product of its base area and height. To get the height, divide the volume by the base area
Perform long division of the volume polynomial by the polynomial for base area to get the polynomial for height
x³+3x²+8 √x⁴+4x³+3x²+8x+4
-x⁴+3x³+8x
---------------------------
1x³+3x²+0+4
- 1x³+3x²+8
------------------------
-4
The answer will be : x+1 + -4/(x³+3x²+8)
