Answer:
Part A: Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.
Part B: Option 3, B: 5x(x+2)(x^2−2x+4)
Step-by-step explanation:
p(x) = 5x^4 + 40x
p(x) = 5x(x^3 + 8)
p(x) = 5x(x + 2)(x^2 - 2x + 4)

Well you have to show us the line plot
5<span>×</span>10^-7 = 0.0000005
When 10 is to a negative power, you move the decimal to the left because the number is less than positive 1. Here 10 is to the power of -7, so you move the decimal (which is after/behind 5) to the left 7 times.
It’s letter D. “Litotes is a figure of speech and a form of understatement in which a sentiment is expressed ironically by negating its contrary.” Hope this helps
4y=3x-24
y=3/4x-6
the line intersect x axis in A
y=0, 3/4x=6, 3x=24, x=8 ⇒ A (8,0)
the line intersect y axis in B
x=0, y=-6 ⇒ B (0,- 6)
a.the gradient of l is 3/4
b. AB= V 6^2 +8^2=V36+64=V100=10
