How to solve 2x(x+3)=2x^2+15

Travka [436]

Answer: x = 5/2 = 2.5

Step-by-step explanation:

<u>Given expression</u>

2x (x + 3) = 2x² + 15

<u>Expand parentheses and apply the distributive property</u>

2x · x + 2x · 3 = 2x² + 15

2x² + 6x = 2x² + 15

<u>Subtract 2x² on both sides</u>

2x² + 6x - 2x² = 2x² + 15 - 2x²

6x = 15

<u>Divide 6 on both sides</u>

6x / 6 = 15 / 6

x = 15/6

$\boxed{x=\frac{5}{2} }$

Hope this helps!! :)

One-half of one-seventh of T equals one-third of one-fifth of 90. What is the value of T

butalik [34]

Answer:

Step-by-step explanation:

This is the equation. Read it carefully.

1/2 * 1/7 T = 1/3 * 1/5 * 90 Reduce

(1/14) * T = 1/15 * 90

1/15 * 90 = 6

(1/14)*T = 6 Multiply both sides by 14

T = 14 * 6

T = 84

sonja wants to have $14000 in 13 years. calculate how much she should invest now at 6% interest, compounded semiannually in orde

mariarad [96]

She should invest $6491.73.

The equation we use to solve this is in the form
$A=p(1+\frac{r}{n})^{nt}$ ,
where A is the total amount in the account, p is the principal invested, r is the interest rate as a decimal, n is the number of times per year the interest is compounded, and t is the amount of time.

A in our problem is 14000.
p is unknown.
r is 6% = 6/100 = 0.06.
n is 2, since it is compounded semiannually.
t is 13.

$14000=p(1+\frac{0.06}{2})^{13*2}
\\
\\14000=p(1+0.03)^{26}
\\
\\14000=p(1.03)^{26}
\\
\\\text{Dividing both sides by }1.03^{26}\text{, we have}
\\
\\\frac{14000}{1.03^{26}}=\frac{p(1.03)^{26}}{1.03^{26}}
\\
\\6491.73\approx p$

on a number line the coordinates of x, y, z, and w are -6, -3, 1 and 4 respectively find the lengths of the two segments below t

exis [7]

The lengths of the two segments below then tell whether they are congruent

YZ = 4

XW = 12

not congruent

This is further explained below.

<h3>What is a number line?</h3>

Generally, A number line is a depiction of a graded straight line that serves as an abstraction for real numbers, which are symbolized by the

Number lines are used in introductory mathematics. It is generally accepted that a real number may be assigned to each point on a number line and that each point can be assigned to a real number.

YZ = Z - Y = 1 -(-3) = 4

XW = W -X = 5 -(-7) = 12

Because the segments are not the same length, they cannot be considered congruent.

In conclusion, It is self-evident that segment YZ will not have the same length as segment XW since it is just a portion of the latter.
