Answer:

x=14.5

Step-by-step explanation:

since we know the sum of a triangles interior angles equal 180, we can subtract 66 from 180

180-66=114

6x-8+2x+6=114 - combine like terms

8x-2=114 - add 2 to both sides

8x=116 - divide by 8

x=14.5

angle a= 79

angle n=35

Zielflug [23.3K]

Answer:

Option A.

Step-by-step explanation:

we have

$x+\frac{b}{2a} =\pm\sqrt{\frac{b^2-4ac}{4a^2}}$

Simplify the right side of the equation

we know that

$\pm\sqrt{\frac{b^2-4ac}{4a^2}}=\pm\frac{\sqrt{b^2-4ac}}{\sqrt{4a^2}}=\pm\frac{\sqrt{b^2-4ac}}{2a}$

The expression is

$x+\frac{b}{2a}=\pm\frac{\sqrt{b^2-4ac}}{2a}$

therefore

x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a

A truck was purchased for $25,000 in 2020 and each year its value decreases by 7%. How much will the truck be worth in

spin [16.1K]

Answer:

$3787.5

Step-by-step explanation:

Given data

Cost price= $25,000

Rate of decrease= 7%

Time= 2020-2026= 26 years

Let us apply the formula

A= P(1-r)^t

substitute

A= 25000(1-0.07)^26

A=25000(0.93)^26

A= 25000*0.1515

A= $3787.5

Hence the worth will be $3787.5
