Answer:

A = 8   B = -2   C = -3

Step-by-step explanation:

The standard form for a quadratic equations is

Ax^2 + Bx +C =0

8x2 - 2x-3=0

A = 8   B = -2   C = -3

skad [1K]

Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

Can someone help me asap
dmitriy555 [2]

Answer:

2) 3 : 15 = 1 : 5

3) 22 : 38 = 11 : 19

4) 2 : 5 = 26 : 65

Step-by-step explanation:

2) 5, 3, 1, 15

3 : 15 = 1 : 5

If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.

3) 19, 22, 11, 38

22 : 38 = 11 : 19

If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.

4) 65, 2, 26, 5

2 : 5 = 26 : 65

If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.

Hope this helps and stay safe, happy, and healthy, thank you :) !!

What is the value of x in the proportion StartFraction 2 x plus 7 over 3 x minus 4 EndFraction equals 11 over 2?
siniylev [52]
(2x + 7) / (3x - 4) = 11/2
cross multiply
11(3x - 4) = 2(2x + 7)
33x - 44 = 4x + 14
33x - 4x = 14 + 44
29x = 58
x = 58/29
x = 2 <===

kati45 [8]

Answer:

Cylinders have two circular bases

Cones have one circular base

The lateral area of a cylinder is related to circumference of the circular bases.

Step-by-step explanation:

In Determining the statements that characterize cylinders and cones. All that apply in this context are :

1) Cylinders have two circular bases

2) Cones have one circular base

3) The lateral area of a cylinder is related to circumference of the circular bases.

Furthermore, in a general context, A cylinder has traditionally been or comprises of a three-dimensional solid, one of the most basic of curvilinear geometric shapes or curves. It is the idealized version of a solid physical tin can which processed lids on top and bottom. While a cone is a three-dimensional geometric shape or a set of line segment that taper smoothly from a flat base (though not necessarily, but mostly circular) to a point called the vertex.
