A teacher writes the following product on the board: (k^2-6)(k^2-5)= k^4-11k^2+30(k 2 −6)(k 2 −5)=k 4 −11k 2 +30

Hello can you me find all the products

Which equation can be used to measure the density of water in a spherical water tank? let w represent the number of water particles within the region.

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3
