Answer:
(x + 1)(x - 1) (x- 2)(x - 5)
Step-by-step explanation:
<u>Solving in steps:</u>
- x^4 - 7x^3 + 9x² + 7 x – 10=
- (x^4 - 1 )- (7x^3 - 7x) + (9x^2 - 9) =
- (x^2 + 1)(x^2 - 1) - 7x(x^2 - 1) + 9(x^2 - 1) =
- (x^2-1)(x^2 + 1 - 7x + 9) =
- (x + 1)(x - 1)(x^2 - 7x + 10) =
- (x + 1)(x - 1)((x^2 - 2x) - (5x - 10)) =
- (x + 1)(x - 1) (x- 2)(x - 5)
First we would find the area of the entire thing,
A=1/2(base)(height)
so A = 1/2(5)(12) = 30 mm^2
next we find the area of the smaller triangle,
A = 1/2(4)(3) = 6 mm^2
Then we subtract the area of the smaller triangle from the area of the larger one
30-6 = 24 mm^2
Answer:
The restaurant cooked 3/10 as many cashews on Tuesday
Step-by-step explanation:
If the word problem says that they used 3/5 of a bag of cashews on Monday, and they used 1/2 AS MANY.
So "as many" gives us a clue to multiply.
3/5 * 1/2 = 3/10
So the restaurant cooks 3/10 bag of cashews on Tuesday
