Answer:
i believe its 1/6
Step-by-step explanation:
Answer:
x = -
, x = 1
Step-by-step explanation:
Given
2x - 5 = - 3x² ( add 3x² to both sides )
3x² + 2x - 5 = 0 ← in standard form
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 5 = - 15 and sum = + 2
The factors are - 3 and + 5
Use these factors to split the x- term
3x² - 3x + 5x - 5 = 0 ( factor the first/second and third/fourth terms )
3x(x - 1) + 5(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(3x + 5) = 0 ← in factored form
Equate each factor to zero and solve for x
3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - 
x - 1 = 0 ⇒ x = 1
Answer:
l= 234/r
Step-by-step explanation:
Given data
Surface area of cone=734.76 square meters.
The formula for the lateral surface area is
S.A=πrl
substitute the surface area
734.76 = 3.14*r*l
734.76/3.14=rl
234=rl
l= 234/r
Hence, with a value for r, the expression for the slant height l is given as
l= 234/r

Hello, Briana so when dividing fractions, its best to put them in decimal form so that you can divide or multiply better. Now having this in mind, 4.25 divided by 1.5 becomes the new equation and using simple math on a calculator, we can conclude that the answer to this question is 1.7 in decimal form or 1 and 7 over 10 in fraction form. Hope this helped, if you have any questions, please ask!
