Mathematics

Answer:

no, they are not.

Step-by-step explanation:

3z means a number multiplied by 3

so if z is 2, 3(2) = 6

but z^3 means z multiplied by z, and then multiplied by z again.

so if z is 2, it's 2x 2 = 4 x 2 = 8

let me know if you have questions

Answer:

No

Step-by-step explanation:

z³ is equivalent to z×z×z while 3z is 3×z.

for example, if z = 2, z³ would become  2³, or 2×2×2 which equals 8.

But 3×2 is 6

so z³ and 3z arent equal

6. Multiply: i) 3x (5x+8y)
Stella [2.4K]

Answer:

Step-by-step explanation:

3x(5x+8y)=15x^2+24xy

4x(3x^2+5x-7)=12x^3+20x^2-28x

(3x+4y)(2x-7y)=6x^2+8xy-21xy-28y^2=6x^2-13xy-28y^2

(2-3a)(2a^2-3a+7)=4a^2-6a+14-6a^3+9a^2-21a=-6a^3+13a^2-27a+14

A 100-foot ramp is tilted at a 45° angle. How high is the top of the ramp from the ground?
BabaBlast [244]
Setting up a right triangle, the 100 would be the hypotenuse, the 45 would be the angle of elevation, and you're looking for the opposite side.
Sin 45 = x/100
100sin45 = x
100 * ✓(2)/2 = x
50 ✓2 =x
x = 50✓2 ft

Alicia is buying 6 oranges that cost $1 per kilogram is it reasonable to say that the cost of the oranges will be greater than $
34kurt

Answer: Yes

Step-by-step explanation:

I am not sure if this is correct, but a kilogram is a very small unit of measure. I would assume that it is greater since 1000kg is equal to 1g. The oranges would have to weigh almost nothing for it to be less than $6.
