How to find out 4 x 754 by using two methods

1 answer:

4 0

You can use expanded form: 4 X 700, 4 X 50, 4 X 4, = 3016.

You can use the Distributive Property of Multiplication: (4 X 500) + (4 X 254) = 3016.

The vertices of ΔGHI are G (2, 4), H (4, 8), and I (8, 4). The vertices of ΔJKL are J (1, 1), K (2, 3), and L (4, 1). Which conc

Klio2033 [76]

Answer:

They are similar by the definition of similarity in terms of a dilation.

Step-by-step explanation:

The first step is finding the sides of each triangle.

In triangle GHI, we have that:

GH = sqrt((4-2)^2 + (8-4)^2) = 4.4721

HI = sqrt((8-4)^2 + (4-8)^2) = 5.6569

IG = sqrt((2-8)^2 + (4-4)^2) = 6

Now, for the triangle JKL, we have:

JK = sqrt((2-1)^2 + (3-1)^2) = 2.2361

KL = sqrt((4-2)^2 + (1-3)^2) = 2.8284

LJ = sqrt((1-4)^2 + (1-1)^2) = 3

The triangles are not congruent, because the sides are different

They are similar, because their sides have a proportion (sides of GHI are 2 times the sides of JKL). If they are similar, they have the same angles.

The ratio of their corresponding sides is 1:2, not 1:3

The ratio of their corresponding angles is 1:1, not 1:3

Help me please I need help!!!!

Answer:

Answer B (proportional)

Step-by-step explanation:

The variable y and x are related by the constant of proportionality "6" in the expression

y = 6 x

Such means that if x adopts whatever value, y is always proportional to that x-value, by the multiplicative factor 6.

y is proportional to x via the proportionality constant (it has to be always a multiplicative constant) "6"

Use elimination to solve each system if equation 3x+2y=0and x-5y=17

kotykmax [81]

Answer:

$y = -3$

$x=2$

Step-by-step explanation:

$3x + 2y = 0$

$x - 5y=17$

to use the elimination you have to make one of the numbers same

$3(x-5y=17)$

and you would have to change the sign so that both of the 3x could cancel out.

New system of equation

$3x + 2y = 0$

$-3x+15y=-51$

$17y=-51$

$y = -3$

so we know the y value so now you could find the x value take one equation

$x - 5y=17$

$x +15=17$

$x = 2$

you could try it with both of the equations

$3x + 2y = 0$

$3x + - 6=0$

$3x-6=0$

$3x=6$

$x=6/3$

$x=2$
