Solve the equation.-4 (y - 2) = 12y = ?

1 answer:

8 0

First you distribute what’s outside the parentheses (the -4)

-4•4= -4y
-4•-2= 8

New equation: -4y+8=12

Now you solve like a normal equation
12-8 is 4

New equation: -4y=4

Now divide

4w^2+4w+1=25 NEED HELP PLEASEEE

geniusboy [140]

Answer:

w=2, -3

Step-by-step explanation:

minus 25 from each side

1+-25+4w^2+4w=25+-25

combine like terms

-24+4w^2+4w=0

factor out the greatest Common factor

4(-6+w+w^2)=0

factor a trinomial

4((-3+-1w)(2+-1w))=0

I hope this helps!

The hypotenuse of a 30o-60o-90o triangle measures 4 square 3 inches. What is the length of the shorter leg?

Fofino [41]

Answer:

The shorter leg is $2\sqrt{3}$ inches

Explanation:

The 30°-60°-90° is a special type of right-angled triangles

It has the following special side length:

The length of the side opposite to the 30° is $\frac{1}{2}$ the length of the hypotenuse

The length of the side opposite to the 60° is $\frac{\sqrt{3} }{2}$ of the hypotenuse

Now, we know that the lengths of the sides in a triangle are proportional to the angles

This means that the shortest side will be the one opposite to the smallest angles

In our case, the shortest side will be the one opposite to the 30° angle

We are given that the hypotenuse of the triangle is $4\sqrt{3}$ in

From the above:

Shorter leg = leg opposite to 30° = $\frac{1}{2} * hypotenuse = \frac{1}{2} * 4\sqrt{3} = 2\sqrt{2}$ inches

Hope this helps :)

Income of the first account after x years:
$1,850(1.026)^x$
Income of the second account after x years:
$2,015(1.015)^x$
Equating the above tw values we get the equation:
$1,850(1.026)^x=2,015(1.015)^x$
Solving the above equation for x:
$x=8$
