Step-by-step explanation:
In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
since there is a term of m^-1 (a negative exponent) that we cannot combine with others (as it is not multiplied with another m-based term), it is NOT a polynomial.
4 | 2x + 7 | = 16...divide both sides by 4
| 2x + 7 | = 16/4
| 2x + 7 | = 4
2x + 7 = 4 -(2x + 7) = 4
2x = 4 - 7 -2x - 7 = 4
2x = -3 -2x = 4 + 7
x = -3/2 -2x = 11
x = -11/2
so x = -3/2 and x = -11/2
Answer:
A) AA postulate; 18
Step-by-step explanation:
Due to the similar triangles, we can set up the proportion and solve for x
8/(8+4) = 12/x
8/12 = 12/x
8*x = 12*12 ... cross multiply
8x = 144
x = 144/8
x = 18
117 divide 3 equals to 39 also they are equal groups as 39 x 3 equals to 117
