Answer:
900 x 2
Step-by-step explanation:
Answer:
(-4,16)
Step-by-step explanation:
1/2x+18=5/2+26
1/2x=5/2x+8
-2=8 divided by -2
Equals x=-4
Plug in -4 in one of the equations
1/2(-4)=18= 16
Step-by-step explanation:
All the sides of the triangle are equal
Therefore, it is a equilateral triangle
and all angles measure 60°.
So, 25x-15= 60
25x = 60+15= 75
x= 75/25
x= 3
2y = 60
y=30
optionA
Answer:
-27a³b⁶+ 8a⁹b¹²
Step-by-step explanation:
In the expression above -27 is a perfect cube of -3, 8 is a perfect cube of 2.
The exponents of a and b in both terms in the expression are divisible by 3.
The cube root of x, that is ∛xⁿ=x∧(n/3) where n is an integer.
