group the common factor

2x + 4

and you'll get 2(x + 2)

For 18x + 6:

You'll do the same thing

18x + 6

What is the angle of B
Charra [1.4K]
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126

so, Angle B is 126 degrees

I hope that helps!

A scale drawing has a scale of 1/4in:12ft. Find the length on the drawing for each actual length. 15 ft.
leonid [27]
So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.

so, what would it be for an actual 15 feet on the drawing then?

\bf \begin{array}{ccll}&#10;\stackrel{inches}{drawing}&\stackrel{feet}{actual}\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;\frac{1}{4}&12\\\\&#10;d&15&#10;\end{array}\implies \cfrac{\quad \frac{1}{4}\quad }{d}=\cfrac{12}{15}\implies \cfrac{\quad \frac{1}{4}\quad }{\frac{d}{1}}=\cfrac{12}{15}&#10;\\\\\\&#10;\cfrac{1}{4}\cdot \cfrac{1}{d}=\cfrac{12}{15}\implies \cfrac{1}{4d}=\cfrac{12}{15}\implies 15=48d\implies \cfrac{15}{48}=d\implies \cfrac{5}{16}=d

The expression sin(23°)cos(7°) + cos(23º)sin(7°) is equivalent to
jeka94

Answer:

\sin(30)

Step-by-step explanation:

Given

\sin(23) \cos(7) + \cos(23) \sin(7)

Required

An equivalent expression

The above is an illustration of the sine formula which states:

\sin(A) \cos(B) + \cos(A) \sin(B) = \sin(A + B)

In this case:

A = 23\\ B = 7

So:

\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(23 + 7)

\sin(23) \cos(7) + \cos(23) \sin(7) = \sin(30)

Hence, an equivalent expression is: \sin(30)
