Answer:
(x + 1) (x^2 + 5)
Step-by-step explanation:
Simplify the following:
x^3 + x^2 + 5 x + 5
Factor terms by grouping. x^3 + x^2 + 5 x + 5 = (x^3 + x^2) + (5 x + 5) = x^2 (x + 1) + 5 (x + 1):
x^2 (x + 1) + 5 (x + 1)
Factor x + 1 from x^2 (x + 1) + 5 (x + 1):
Answer: (x + 1) (x^2 + 5)
Answer:
187 cm²
Step-by-step explanation:
The bottom rectangle area is easy, it is 15*9 = 135 cm².
To find the area of the triangle, you only need the base width and its height (you don't need the hypotenuse). You can then use the formula: area triangle is base times half height.
The base width is 15-7 = 8 cm
The height is 22-9 = 13 cm
So the area of the triangle is 13*8/2 = 52 cm²
Together with the 135 of the rectangle that sums to 52+135 = 187 cm².
Since david ate a quarter of the pizza he ate 3 slices. John ate 4 slices. 4+3=7 , 12-7=5 pieces of pizza are left
