√(15+x) = 2x+3
take sqr for both side

15x+10=(2x+3)^2

15x+10=4x^2+9+2*2x*3
15x+10=4x^2+9+12x
4x^2-3x--1=0

solve it u will x=1,-1/4

soldier1979 [14.2K]

\large \mathfrak{Solution : }

Common difference of an Arithmetic progression can be found out by subtracting the preceding term from that given term.

i.e

  • common \:  \: difference = 4 - 8
  • common \:  \: difference =  - 4

therefore, the common difference of the above Arithmetic progression is -4 .

TIMED!!!
guajiro [1.7K]

Answer: Last option.

Step-by-step explanation:

The total amount of concrete in the ramp (V_t) will be the sum of the volume of the  rectangular prism (V_{rp}) and the volume of the triangular prism (V_{tp})

V_t=V_{rp}+V_{tp}

The formulas are:

V_{rp}=lwh

Where "l" is the lenght, "w" is the width and "h" is the height.

 V_{tp}=\frac{bhl}{2}

Where "l" is the lenght, "b" is the base and "h" is the height.

Substituting, we get:

V_t=V_{rp}+V_{tp}\\\\V_t=lwh+\frac{bhl}{2}\\\\V_t=(18in)(6in)(6in)+\frac{(8in)(6in)(18in)}{2}\\\\V_t=1,080in^3
