I calculated the percents. 6% of $42 is $2.52 and I wrote that down .Then 20% of $42 is $8.4. I added those to the $42 and got $52.92
So we say x=-2
so in the equation where ever we see x we plug in like
f(-2)= 2 * (-3)^3 + 3 * (-2)^2
= 2 * -8+ 3 * 4
= -4
(-2,-4)
hope that helps
Answer:
B. 46 ft²
Step-by-step explanation:
Two sides are rectangles 3.1 ft by 5 ft.
One side is a rectangle 5 ft by 3 ft.
area = 2(3.1 ft × 5 ft) + (5 ft × 3 ft)
area = 46 ft²
ANS to 25 times 10^6
