Determine if y=4x2−5 is linear, quadratic, or exponential.
Group of answer choices

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
