You divide each side of the equation by 4 .
Then you have

<em>x = 15/4</em>  or  3.75

Yeah AL2006 was right you have to divide 4 on both sides because when a variable is connected to a number like that with no sign between them it is multiplication and the opposite of multiplication is division and 4 divided by 4 cancels out because it is 0. 15 divided by 4 is 3.75.

A turtle laid 70 eggs and 9/15 hatched how many did not hatch
slavikrds [6]

Answer:

<h2><u>28 eggs did not hatch.</u></h2>

Step-by-step explanation:

<h3>1) Calculate 9/15 of 70 eggs. </h3>

\frac{9}{15}  × 70

= \frac{630}{15}

= 42

<h3>2) To calculate how many eggs <u>DID NOT</u> hatch, we should subtract 42 from 70.</h3>

70 - 42 = 28

<u>28 eggs did not hatch.</u>

Write a polynomial function of least degree with integral coefficients that has the given zeros. 4, -6, 1
german

Answer: f(x) = x³ + x² - 26x + 24

<u>Step-by-step explanation:</u>

x = 4             x = -6              x = 1

x - 4 = 0        x + 6 = 0         x - 1 = 0

(x - 4) (x + 6) (x - 1) = 0

(x² + 2x - 24)(x - 1) = 0

x(x² + 2x - 24)  -1(x² + 2x - 24) = 0

x³ + 2x² - 24x  -x² - 2x + 24  = 0

x³ + x² - 26x + 24 = 0

For the function: f(x) = 21 + 2x − 5x2<br> Find f(3)
allochka39001 [22]
F(3)=-18

You just replace x for three for your equation and then use Ofer of operations to solve it.

So f(3)= 21+ 2(3)-5(3)^2

The exponent goes first: f(3)= 21+ 2(3)-5(9)

Next is multiplication: f(3)= 21+ 6-45

Now add: f(3)= 27-45

Finally subtract: f(3)= -18

Hope this helps!
