Answer:
5x^7y^11.
Step-by-step explanation:
∛(125x^21 y^33)
The cube root = 'to the power 1/3' so we have:
125^1/3 * x^(21*1/3) * y^(33*1/3)
5x^7y^11.
Answer:
3rd option - 14 m²
Step-by-step explanation:
First we know that the square's area will be 2×2 = 4
To calculate the area of a triangle we know the vertical height is 2.5 and the base length is 2 so we can use the formula b×h/2 to give the area of one triangle:
2.5×2 = 5
5÷2 = 2.5
So the area of 1 triangle is 2.5 m²
Since there are 4 triangles we multiply the area of 1 traingle by 4:
2.5×4 = 10
We add the area of the 4 triangles to the area of the square to give our final answer of :
10 + 4 = 14
14 m²
The answer is 6 since 2*6 is 12 and 12-8 is 4
Answer:
18 ft
Step-by-step explanation:
Since the triangle is right angled ; we could use trigonometry ;
Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x
Cos θ = Adjacent / hypotenus
Cos 40 = 14 / x
0.7660444 = 14 / x
0.7660444x = 14
x = 14 / 0.7660444
x = 18.27
= 18 ( nearest foot)
Answer:
y=12
Step-by-step explanation:
Use order of operations. Subtract 18 from both sides and the divide by 2.
2y+18 -18=42-18
2y=24
y=12
