Yes, it is true (I’m pretty sure, same shape etc)
Answer:

Step-by-step explanation:
Simplify the expression

Calculate the product of the coefficients:
2*5*7=70
Compute the product of the variables. Since they are all the same letter, sum their exponents:

Combine the results:

Your answer would be
A. Adding 7x to both sides of the equation
And in doing so, you'd start your first step to having "like terms" on "like sides"
by having all "x's" on the right side of your equivalent sign "="
Answer:
a, ax3 =b, bx3= c , cx3=d, dx3=e
Step-by-step explanation:
2, 2×3=6, 6x3=18,18 x3 =54, 54x3= 162
Multiplication of three with previous number will give you next number in series.
