Lets check all the choices:
A. subtraction:
(3x+2)-(4y-11)=3x+2-4y+11=3x-4y+13
similarly, (4y-11)-(3x+2)=-3x+4y-13
both are polynomials (of 2 variables)
B. (3x+2)(4y-11)=12xy-33x+8y-22, which is a polynomial
C. (3x+2)+(4y-11)=3x+2+4y-11=3x+4y-9, which is a polynomial
D.
both
and
are rational expressions in 2 variables, not polynomials
Answer: D
It is a linear equation so there can be 1 solution, 0 solutions, or infinite solutions
4(x-5)=4x-24
distribute
4x -20 = 4x-24
subtract 4x from each side
-20 = -24
no solutions
A) 14.66
Arc length is equal to radius multiplied by the central angle in radians not degrees
Answer:
She missed her goal, because she made less than $75 on coffee today.
Step-by-step explanation:
Gabriela, did not meet her goal because she only mad 72$ today
if you do
80 cents times 90 cups you only get 72$
meaning that she was 3$ short from meeting her goal.
.80 * 90
Take out common numbers/variables in both terms;
6x(x³-27)
Hope I helped :)
