The constant of proportionality is <em>4 .</em>

The equation is  [ <em>Height = (4) times (Days)</em> ] .

When the sunflower is 60cm tall,                60 = (4) times (Days).

Divide each side of the equation by 4:       <em>15  =  Days</em>

<span>Así que la suma de los cientos y miles será dos veces el dígito de las unidades . Miles ( 7 ) + cientos ( 1 ) = 8. 8 es dos veces más que el dígito de las unidades ( 4) de los miles de diez dígitos es el mismo que el de un dígito es así, esto hace que los miles a decenas 4 también .

How do you find the complete square of a math problem
dolphi86 [110]

Step-by-step explanation:

I am not sure what exactly you mean.

do you mean the complete square of an expression or

term ?

if so, then by multiplying this term by itself, and that means in general, every part is multiplied by every part and the part results are added considering the signs involved.

e.g.

squaring a+b

(a+b)(a+b) = a×a + a×b + b×a + b×b = a² + 2ab + b²

remember that multiplication and addition are commutative (you can flip the right and left sides with each other and still get the same result : a+b = b+a, a×b = b×a).

squaring a-b

(a-b)(a-b) = a×a + a×-b + -b×a + -b×-b = a² - 2ab + b²

remember that

+×- = -×+ = -

-×- = +

+×+ = +

a more complex example ?

squaring a-b+c

(a-b+c)(a-b+c) =

= a×a + a×-b + a×c + -b×a + -b×-b + -b×c + c×a + c×-b + c×c =

= a² - 2ab - 2bc + 2ac + b² + c²

Lines,rays,and segments
tino4ka555 [31]

Answer: line: To represent straight objects in geometry, mathematicians introduced the concept of line or straight line

rays: vector, a ray is a vector from a point to a point. In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and taken to be at infinity

segments: The term line segment refers to a section of a line bounded by two distinct points. It is comprised of all points on the line between its endpoints. A closed line segment includes both endpoints, whereas an open line segment excludes both endpoints.

Solve the following system of equations. What is the x-value of the solution?
Leni [432]

Answer:

x = 1

Step-by-step explanation:

<u>Step 1:  Choose one of the equations to solve for y:</u>

x - y + 1 = 0

(-y) / -1 = (-1 - x) / -1

y = 1 + x

<u>Step 2:  Plug in y into either equation</u>

3x + 2(1 + x) = 7

3x + 2 + 2x - 2= 7 - 2

5x / 5 = 5 / 5

x = 1

Answer:  x = 1
