Answer:
1+0
Step-by-step explanation:
because your adding
we can do the same here as you saw before, but using long division to check the remainder, hmmm so f(-2), meaning x = -2 for an expression of x + 2 = 0, so let's firstly divide f(x) by x + 2 using long division, will be the same as synthetic, but just to check, then we'll see what f(-2) is.
Check the picture below.
f(-2) = 4(-2)³ - 2(-2)² +3(-2) - 2
f(-2) = -48
Q1. The answer is 4(2x - 3)(2x + 1)
16x² – 16x – 12 = 4 * 4x² - 4 * 4x - 4 * 3 =
= 4(4x² - 4x - 3) =
= 4(4x² + 2x - 6x - 3) =
= 4(2x * 2x + 2x - (2x * 3 + 3)) =
= 4(2x(2x + 1) - (3(2x + 1))) =
= 4((2x + 1)(2x - 3)) =
= 4(2x - 3)(2x + 1)
Q2. The answer is 3(x + 8)(x - 1)
3x² + 21x – 24 = 3 * x² + 3 * 7x - 3 * 8 =
= 3(x² + 7x - 8) =
= 3(x *x - x + 8x - 8) =
= 3((x(x - 1) + 8(x - 1)) =
= 3(x + 8)(x - 1)
Answer: 20 bars
Step-by-step explanation: If the van can hold up to 1200kg and each bar weighs 60kg, you would divide 1200kg/60 kg and get the answer of 20.
You'd have to include a picture of the figure. A rotation moves it around a fixed point, a translation moves it left, right, up, or down without changing the direction it faces or its size. A reflection is a mirror image and a dilation changes its size.
