Answer:

$6 {d}^{2} + 5cd - 3dc + 8$

Step-by-step explanation:

b/c we can substructure 5cd and 3dc b/c it doesn't matter if the place of cd and dc change. what I mean if 5 ×3=15 and it is the same with 3×5=15 both of the product are the same but, if it is - and ÷ it wil be wrong for example 5-3=2 but 3-5= -2

if is helpful ❤❤

Arif's backyard is 22 by 36 meters. He wants to put a flower garden in the middle of the backyard, leaving a strip of grass of u

KIM [24]

Answer:

Paso 1:

Encuentra el área del patio trasero

Dado eso, el patio trasero mide 24 por 30 metros.

Área = largo x ancho

Área = 24 x 30 = 720

Por lo tanto, el área del patio trasero es de 720 metros cuadrados.

Paso 2:

Dado que el área de césped = 368 metros cuadrados

Luego, área de jardín = área de patio trasero - área de césped

área del jardín = 720 - 368

área de jardín = 352 metros cuadrados

Paso 3:

Encuentra las dimensiones del jardín

Sea "x" el ancho de la franja de césped

Entonces, las dimensiones del jardín son:

Longitud del jardín = 24 - 2x

Ancho del jardín = 30 - 2x

Luego,

área del jardín = (24 - 2x) (30 - 2x)

Factoriza el lado izquierdo

(x - 23) (x - 4) = 0

Por propiedad de factor cero,

x = 23 o x = 4

La solución x = 23 hace que las dimensiones del jardín sean negativas, por lo que la rechazamos

makkiz [27]

96 times 5.3 divide by 60, equal to 8.48 minutes, the third choice is correct

Help!!!!!!!!!!!!!!!!!!!!????

1. 77 mph
We already know they travel 38.5 miles in 30 minutes. So we multiply 38.5 x 2 because 30 minutes is 1/2 of an hour. 38.5 x 2 = 77

5. 8.5 minutes (8 minutes and 30 seconds) per mile
We have to divide 25.5 by 3 to know how many minutes it takes Jerry to run one mile.

8. 34.06
This one is kinda easier. We already know 34 is the whole number. 6 divided by 100 is 0.06, so we simply add 34 + 0.06

Hey guys I have a question now if you have an 84% and you get an 105% on an assignment then you get another 105% on an assignmen

soldier1979 [14.2K]

You have to find the average so you add up all of the numbers and divide by how many there are. So it would be:

84+105+105+100=394
394/4= 98.5

So your grade would be about 98.5%
