Answer: 1.79

Step-by-step explanation: x2−6x−14=0

For this equation: a=1, b=-6, c=-14

1x2+−6x+−14=0

Step 1: Use quadratic formula with a=1, b=-6, c=-14.

x=

−b±√b2−4ac

2a

x=

−(−6)±√(−6)2−4(1)(−14)

2(1)

x=

6±√92

2

x=3+√23 or x=3−√23

Answer:

x=3+√23 or x=3−√23= 1.79

You have 10 fewer quarters than dimes and 5 fewer nickels than quarters. the total value of the coins is $4.75. Set up a system
Yanka [14]
So 
x- quarters
y - dimes
z- nickels

The system of equations would be
x+10=y
z+5=x
x+y+z= 4.75

What is the x-intercepts of y= -2(x-3)[2]+2?
mrs_skeptik [129]

Answer: (x,y)=(14/4,0)

Step-by-step explanation:

y=-2(x-3)(2)+2

Clear the brackets

y=-2(2x-6)+2

y=-4x+12+2

y=-4x+14

To get the x-intercept y=0

0=-4x+14

4x=14

x=14/4

(x,y)=(14/4,0)

Ben made a model (shown below) of the square pyramid he plans to build when he grows up.
elena-s [515]

Answer:

336 m^2

Step-by-step explanation:

The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

A=A_b + 4A_t

where:

A_b=L^2 is the area of the base, where

L is the length of the base

A_t=\frac{1}{2}Lh is the area of each triangular face, where

h is the height of the face

Substituting,

A=L^2+2Lh

For the model in this problem,

L = 12

h = 8

Therefore, the surface area here is:

A=12^2 +2(12)(8)=336
