Answer:
13.416 or 13.4
Step-by-step explanation:
True
4x^2 -16x +16 = (2x -4)^2
A = 2x
B = 4
10xy+2y+8x+7
Explanation
3xy + 4xy + 3xy = 10xy
The others cant be simplified so
10xy + 2y + 8x + 7
Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
Answer:
520
Step-by-step explanation:
a=8
b=2
8+2=10
8-2=6
8³=512
2³=8
512+8=520
