Answer:
1, and 3 are equivelent to (3)^4(10)^4
Step-by-step explanation:
(3)^4(10)^4 = 810000
1. (3^2)^2 * (10^2)^2
(9)^2 * (100)^2
81 * 10000
810000
2. (13)^4 = 28561
3. (3 * 10)^4
(30)^4
810000
Answer:
9
Step-by-step explanation:
22x = 198
divide both sides by 22
22x/22 = 198/22
x = 9
Answer:
20 + 4y
Step-by-step explanation:
The 4 multiplies the 5 and the y, i.e., it distributes over the terms of the expression in ( ).
120 + 120 + X + X = 360
240 + 2X = 360
2X = 120
X = 60
Answer:
area of the figure: 29.92 m²
formula's:
- area of rectangle: length * width
- area of sector: ∅/360 * πr²
solving steps:
area of rectangle + area of sector
5.5 * 4 + 30/360 * π(5.5)²
22 + 7.919
29.92 m²
