Which is larger 2/3" x 3-7/16" or 0.6"L x 3.43"W?
Darina [25.2K]
2/3 x (3 - 7/16) = (2/3) * (3+7/16)
       = (2/3)*(55/16)
       = 55/24
       = 2.2917

0.6 x 3.43
      = 2.058

The first answer is greater than the second.

Answer:  2/3 x 3-7/16 is larger.

I can't figure out how to solve for x
Romashka [77]
The answer i got was x=2 :)

Step 1: Simplify both sides of the equation.
x−2 over 3−(x+3 over 5)=−1
Simplify: (Show steps)
2 over 15x+−19 over 15=−1
Step 2: Add 19/15 to both sides.
2 over 15x+−19 over 15+19 over 15=−1+19 over 15
2 over 15x=4 over 15
Step 3: Multiply both sides by 15/2.
(15 over 2)*(2 over 15x)=(15 over 2)*(4 over 15)

What are the rational roots of the polynomial f(x) = 20x^4 + x^3 +8x^2 + x-12
Natali5045456 [20]

Answer:

x = 3/4 and x = -4/5

Step-by-step explanation:

20x⁴ + x³ + 8x² + x − 12

Group:

(20x⁴ + 8x² − 12) + (x³ + x)

Factor:

4 (5x⁴ + 2x² − 3) + x (x² + 1)

4 (5x² − 3) (x² + 1) + x (x² + 1)

(x² + 1) (4 (5x² − 3) + x)

(x² + 1) (20x² + x − 12)

(x² + 1) (4x − 3) (5x + 4)

So the rational roots are x = 3/4 and x = -4/5.

I need step by step instructions on how to get the y-intercept: -210 for f(x)=x^3-18x^2+107x-210.
Mrrafil [7]
Y=f(X)
At y-intercept, X=0
f(X)= 0^3-18(0)^3+107(0)-210
= -210
