Answer:
10 by 4
Step-by-step explanation:
10 is 6 units greater than 4
and
10 times 4 is 40
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = 
+ 3x³ - 4x²
To find the zeros equate f(x) to zero, that is
+ 3x³ - 4x² = 0 ← factor out x² from each term
x²(x² + 3x - 4) = 0 ← factor the quadratic
x²(x + 4)(x - 1) = 0 ← in standard form
Equate each factor to zero and solve for x
x² = 0 ⇒ x = 0 with multiplicity 2
x + 4 = 0 ⇒ x = - 4
x - 1 = 0 ⇒ x = 1
zeros are x = - 4, x = 0, x = 1

Answer:
7
Step-by-step explanation:
The degree of each term is the sum of the degrees of the variables in it.
Term, Degrees
-5, 0
-5x^2wy^4, x:2, w:1, y:4 -- term degree = 2+1+4 = 7
-y^4x^2, y:4, x:2 -- term degree = 4+2 = 6
-4w^3, w:3 -- term degree = 3
The highest of these is 7, so the degree of this polynomial is 7.
Answer:
a) x=2
b)x=12
c)x=5/4
Step-by-step explanation:
a)5x-2=8
5x=8+2
5x=10
x=2
b)4x-3=2x+9
4x-2x=9+3
2x=12
x=6
c)6x+3=2x+8
6x-2x=8-3
4x=5
x=5/4
Proof:
a)5x-2=8
5(2)-2=8
10-2=8
8=8
b)4x-3=2x+9
4(12)-3=2(12)+9
48-3=24+9
45=45
c)6x+3=2x+8
6(5/4)+3=2(5/4)+8
30/4+3=10/4+8
15/2+3=5/2+8
10.5=10.5
Hope this helps ;) ❤❤❤
