Answer:
3x^3 +14x^2 +2x +35
Step-by-step explanation:
The distributive property is used to find the product of polynomials. Terms can be collected to express the result with terms in order of decreasing degree.
__
(3x^2 -x +7)(x +5)
= x(3x^2 -x +7) +5(3x^2 -x +7) . . . . apply the distributive property
= (3x^3 -x^2 +7x) +(15x^2 -5x +35) . . . . show the products
= 3x^3 +(-1 +15)x^2 +(7 -5)x +35 . . . . . collect like terms
= 3x^3 +14x^2 +2x +35 . . . . . . . . write in standard form
1. distribute the 3 into the variable and number in the equation
to do this..
2. multiply 3 by x (obtain the answer of 3x)
3. multiply 3 by -2 (obtain the answer of -6)
4. you now have the equation of ‘14 = 3x-6+5’
5. subtract 6 from 5 (obtain the answer of -1)
6. you now have the equation of ‘14 = 3x-1’
7. add one to both sides (cancel out the negative one and make the opposite side of the equation 15 instead of 14)
8. you now have the equation of ‘15 = 3x’
9. divide both sides by 3 (15 and x)
FINAL ANSWER
x = 5
hope this helps:)
A^2 + 9 = 36 now solve subtract 9 from both sides to get a^2 = 27 then find the square root of 27 and that should be your answer so like 5.196 something
The integers or -3, -2, -1,0, and 1
