It's 9. Take 81/9 and that equals nine
Answer:
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 degrees
so
70 + 35 + x = 180 add like terms
105 + x = 180 subtract 105 from both sides
x = 75

Step-by-step explanation:
22
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
