Question

two models are given for the number of students of males and females that attend institutes of higher education in the us. add the two models together to get a total number of people attending institutes of higher education. model 1: $0.12z^{3}+8.3z^{2}+127z + 155425$ model 2: $0.14z^{3}+5.7z^{2}+181z + 124950$ enter an algebraic expression more...

Explanation:

Step1: Combine like - terms of $x^3$

$(0.12x^{3}+0.14x^{3})=(0.12 + 0.14)x^{3}=0.26x^{3}$

Step2: Combine like - terms of $x^2$

$(8.3x^{2}+5.7x^{2})=(8.3 + 5.7)x^{2}=14x^{2}$

Step3: Combine like - terms of $x$

$(127x+181x)=(127 + 181)x=308x$

Step4: Combine constant terms

$(155425+124950)=280375$

Step5: Write the final polynomial

$0.26x^{3}+14x^{2}+308x + 280375$

Answer:

$0.26x^{3}+14x^{2}+308x + 280375$
