A. The area of a square is given as:
<span>A = s^2 </span>
Where s is a measure of a side of a square. s = (2 x – 5)
therefore,
<span>A =
(2 x – 5)^2 </span>
Expanding,
A =
4 x^2 – 20 x + 25
<span>B.
The degree of a polynomial is the highest exponent of the variable x, in this case
2. Therefore the expression obtained in part A is of 2nd degree.</span>
Furthermore,
polynomials are classified according to the number of terms in the expression.
There are 3 terms in the expression therefore it is classified as a trinomial.
<span>C.
The closure property demonstrates that during multiplication or division, the
coefficients and power of the variables are affected while during
multiplication or division, only the coefficients are affected while the power
remain the same.</span>
Answer:
it would be 5
Step-by-step explanation:
Answer: Y =24
Step-by-step explanation:first get the constant. X=KY substituting x and y in the equation is 3=K8 Therefore K = 3/8 =0.375
If x is 9 find y when the constant k is 0.375 from the equation x=ky
Is Y = X÷K is 9÷0.375 =24.
Answer:
14x²(2x³ + 1)
Step-by-step explanation:
Split the value: 28x⁵
28x⁵ = 28x³x²
14x² + 28x³x²
28 = 14 × 2
14x² + 14 · 2x³x²
Factor:
14x²(2x³ + 1)
