8(x-3) = x + 25
8x -24 = x + 25
7x = 49
x = 7

X= the numbers
8(x-3)=x+25
distribute
8x-24=x+25
minus x both sides
7x-24=25
add 24 both sides
7x=49
divide both sides by 7
x=7

the numbers is 7

Solve the following exponential equations. 4^x + 7(2^x) + 12 = 0

andrey2020 [161]

Answer:No value of x

Step-by-step explanation:

Given

$4^x+7(2^x)+12=0$

Let $2^x=y$

$y^2+7y+12=0$

$y^2+3y+4y+12=0$

$y(y+3)+4(y+3)=0$

$(y+3)(y+4)=0$

$y=-3,-4$

$2^x=-3$

or $2^x=-4$

so there is no value of x for which $2^x=-3 or -4$

because minimum value of $^x=1$

I need help with this math problem

Dovator [93]

Teh value of x is 23° (D)

Step-by-step explanation:

Total of angel = 360°

The value of x :

(2x + 15)° + 119° + 99° + 81° = 360°

2x + (15 + 119 + 99 + 81)° = 360°

2x + 314° = 360°

2x = 360° - 314°

2x = 46

x = 46 ÷ 2

x = 23°

So, the value of x is 23° (D)

Hope it helpful and useful :)
