Find the value of x.<br> (9x+8)<br> 37°

gulaghasi [49]

Total angles on a straight line
(9x + 8) + 37 = 180
9x + 45 = 180
9x = 180 - 45
9x = 135
Divide through by 9
x = 15

Solve the following equations for x, if possible. check your solutions. 6/dividex+2 = 3/4

SOVA2 [1]

Solving $\frac{6}{x+2}=\frac{3}{4}$ we get x=6

Step-by-step explanation:

We need to solve $\frac{6}{x+2}=\frac{3}{4}$

Solving:

Cross multiply both terms:

$4*6=3(x+2)\\24=3x+6\\3x=24-6\\3x=18\\x=18/3\\x=6$

Verifying the solution:

Putting x=6 in the question given:

$\frac{6}{x+2}=\frac{3}{4}$

$\frac{6}{6+2}=\frac{3}{4}$

$\frac{6}{8}=\frac{3}{4}$

$\frac{3}{4}=\frac{3}{4}$

Solving $\frac{6}{x+2}=\frac{3}{4}$ we get x=6

Help please, kind of confused

Anvisha [2.4K]

Answer:

Step-by-step explanation:

Yikes. This is quite a doozy, so pay attention. We will begin by factoring by grouping. Group the first 2 terms together into a set of parenthesis, and likewise with the last 2 terms:

$(2d^4+6d^3)-(18d^2-54d)$ and factor out what's common in each set of parenthesis:

$2d^3(d+3)-18d(d+3)$ . Now you can what's common is the (d + 3), so factor that out now:

$(d+3)(2d^3-18d)$ BUT in that second set of parenthesis, we can still find things common in both terms, so we continue to factor that set of parenthesis, carrying with us the (d + 3):

$(d+3)2d(d^2-9)$ BUT that second set of parenthesis is the difference of perfect squares, so we continue factoring, carrying with us all the other stuff we have already factored:

$(d+3)2d(d+3)(d-3)$ . That's completely factored, but it's not completely simplified. Notice we have 2 terms that are identical: (d + 3):

$2d(d+3)^2(d-3)$ is the completely factored and simplified answer, choice 3)
