Answer 1

Answer: (4x^2-25)/(2x-5)=14
we hates fractions so m ultiply both sides by (2x-5)
4x^2-25=14(2x-5)
4x^2-25=28x-70
add 70 to both sides
4x^2+45=28x
subtract 28x fromoth sides
4x^2-28x+45=0
use quadratic formula which is
if you have
ax^2+bx+c=0 then
x= $\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}$
a=4
b=-28
c=45
subsitute
x= $\frac{-(-28)+/- \sqrt{(-28)^(2)-4(4)(45)} }{2(4)}$
x= $(28+/- √(784-720) )/(8)$
x= $(28+/- 8)/(8)$
x= $(5)/(2)$ or $(9)/(2)$
if we were to put 5/2 for x, the deonomentor would be equal to zero, so it cannot be used

answer is
x=9/2

Write an algebraic expression for the phrase:six times a length w

Answers

Six times a length w means that we will repeat the w six times.

This can be expressed algebraically in two ways:
1- using addition:
six times a length w = w+w+w+w+w+w
2- using multiplication:
six times a length w = 6*w

3.14*9*9*14=3,560.76

3,560.76/3=1,186.92 (3,052.1)

3.14*9*9*4=9,156.24

9,156.24 /3=3,052.08(3,052.1)

3,052.1+3,052.1=6104.2
