Answer:
1 < x < 17
Step-by-step explanation:
9, 8
Third side should be less than 9 + 8 = 17
And it should be greater than 9 - 8 = 1
<h2><u>AnswEr :</u> </h2>
The area of the rectangle is of the form 6x² - 9x - 15
Factoring the given expression,

Length of the rectangle is 2x - 5
Thus,

<h3>The breadth of the rectangle is 3x + 3 </h3>
Answer:
x=2 or x=-2
Step-by-step explanation:
I'm not sure what you're asking, but when you solve, set both sets of parentheses equal to 0 and solve. This makes x either equal to 2 or -2.
3x²+x-5=0
a = 3, b = 1, c= -5
-> ∆ ( delta ) = b²-4ac = 61 > 0
-> x1 =( -b+√∆ )÷ 2a =...
x2 = (-b-√∆)÷2a =...
p/s: do your teachers teach you how to use ∆ ( delta ) in maths calculation ? i live in europe and our teachers teach us that way. however, it is a rịght and fast way. you should learn it.
Answer:
Step-by-step explanation:
a+pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
a= 353.25ft^2
