Answer:
d and e
Step-by-step explanation:
To factor 4x² + 17x - 15
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, that is
product = 4 × - 15 = - 60 and sum = + 17
The factors are + 20 and - 3
Use these factors to split the middle term
4x² + 20x - 3x - 15 ( factor by grouping the first/second and third/fourth terms )
= 4x(x + 5) - 3(x + 5) ( take out the common factor (x + 5) )
= (x + 5)(4x - 3) → d/e
The radius of the given circle with a central angle of 7π/10 and arc length of 33cm is 15cm.
It is given that
The central angle of the given circle = 7π/10 radians
Length of arc = 33cm
<h3>What is the formula for arc length?</h3>
Arc length = central angle* radius
From the above formula
Radius = Arc length/Central Angle
Radius = 
Radius = 15cm
Therefore, radius of the given circle is 15cm.
