ok, i will keep this in mind but i 'm glad i got it right, well, some what! Thank you, i wish i had your brain :D

solve using the five step problem solving process, translate, reword, carry-out, check, and state. An object altitude, in meters is given by the polynomial ht+vt-9.8t^2 where h is the height in meters from which the launch occurs. v is the initial upward speed in meters per second and t is the...

divide (8x^2 +65x -63) / (x+9) x+9/(x+9)(8x-7) 1/8x-7 if this is not right, please show me in steps so i can practice and study it.

MULTIPLY (x+1/2) (x^2 +4x +1/2)= (x^2 +4x +1/2) +(1/2) (x^2 +4x +1/2) (x+1/2) (x^2 +4x -1/2)= (x^3 +4x^2 +(x/2) + (x^2 +2x +1/4) (x+1/2) (x^2 +4x +1/2)= x^3+ (4+1/2)* x^2+(2 +1/2) * x +1/4 (x+1/2) (x^2 +4x +1/2)= x^3+ (9/2)* x^2+ (9/2)* x^2+ (5/2) * x +1/4

-x^3 +x^2 +42 (x-7) (x^2-6) answer x^3 -6x-7x^2 +42 factor answer x^3 -x^2 +42 am i close or correct?

Use the five step problem solving process, an object altitude in meters is given by the polynomial h+vh-9.8t^2 which h is the height in meters from which the launch occurs. V is the initial upward speed in meters per second, and t is the number from which the rocket is airborne. A pebble is...

Thank you but i haven't been in school in over 20 years and haven't yet used a formula for anything except now. :D

factor completely -x^3 +x^2 +42x (x -6) (x -7)

multiply (x+2/3) (x-2/3) x^2 -2/3x +2/3x -4/6 x^2 -4/6

Sadly, that's the whole problem, i checked.

No, i do not know the famous formula for calculating the area of the rectangle.

solve using the five step problem solving process, translate, reword, carry-out, check, and state A 3-ft. by 5-ft. picnic table is placed on an outdoor patio measuring x ft by (x+1). find the polynomial for the remaining open space on the patio (in square ft.) I do not understand this...

solve using the five step problem solving process, translate, reword, carry-out, check, and state. an object's attitude in meters is given by the polynomial ht vt -.8t^2 huh, how do i get started, i do not understand this?

(x-3) (7x^2 +x +8) x-3 / 7x^2 +x +8 first, x/7x^2 =7x i would put the 7x on top over the 7x^2 then subtract 7x^2 +x 7x^2 -3= -3x +8 3x/ -3x +8= 3 whci goes at the top 7x -3 -3x -9= 1 answer 7x-3 reminder 1 i could do it better if i could show you in writing. -3x +8

subtract (3x^4 +4x^3 +7) - (x^4 -2x^3 +x^2 -9) 3x^4 +4x^3 +7 -x^4 +2x^3 -x^2 +9 answer 2 +6x^3 -x^2 +16

evaluate the ploynomial, 9x +6 for x= 4 9(4) +6 36 +6= 42

thank you for your advice and help, i won't muiltiply the exponents when i'm adding or subtracting.

I got to be more careful with the signs, i wish i had your brain. Thank you for your help. I will try to be more attentive to my work.

2x^2y -xz^3 for x= -3 y= 1 z= 3 2(-3)^2(1) -(-3)3^3 2(9) (1)+(3) (27) 18*1 *+81 18+81= 99

divide (8x^2 +65x -63) / (x+9) x+9/ 8x^2 +65 -63 8x^2 +63 2 -63 2-65= 2 amswer 4x^2 +9
