Mathematics
1 answer:
Bess [88]2 years ago

Answer:

(4x + 5)(4x - 3)

Step-by-step explanation:

Given

16x² + 8x - 15

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 16 × - 15 = - 240 and sum = + 8

The factors are + 20 and - 12

Use these factors to split the x- term

16x² + 20x - 12x - 15 ( factor the first/second and third/fourth terms )

= 4x(4x + 5) - 3(4x + 5) ← factor out (4x + 5) from each term

= (4x + 5)(4x - 3) ← in factored form

What is the volume of the solid if a 6 inch (diameter hole is drilled all the way
Tanzania [10]

Answer:

1,467.6 cm³

Step-by-step explanation:

Volume of the solid = volume of the rectangular prism - volume of the cylinder

= L*W*H - πr²h

L = 12

W = 10

H = 16

r = ½(6) = 3

h = 16

Plug in the values

Volume of the solid = 12*10*16 - π*3²*16

= 1,920 - 452.40

= 1,467.6 cm³

The equation of a circle in standard form is ...

  (x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r

The graph shows your circle has its center at (1, 4) and its radius is 5. Then the equation is ...

  (x -1)² +(y -4)² = 25

Answer:

5<b-3

Add 3 on both sides

8<b

The variable will always go on the left side of the equation. To flip the equation, you must also flip the less than sign to a greater than sign.

b>8
