Answer:

Step-by-step explanation:

Expand the factors and compare the coefficients of like terms.

Given

(mx + 2)(3x - 5) ← expand using FOIL

= 3mx² - 5mx + 6x - 10

Compare to 12x² - 14x - 10

For the 2 to be equal, then the coefficients of like terms must be equal.

Compare coefficients of x² terms

3m = 12 ( divide both sides by 3 )

m = 4 → C

Marcia claims that the GCF for (2x2 + 4xy + 8xy4) is 8x2y4.

miskamm [114]

She is not correct.
The GCF for 2x^2 + 4xy + 8xy^4
is 2x
The first term does not have a 'y' in it so you cannot have a 'y' in the GCF.
The second and third terms both only have 1 'x', so you can only take out 1 'x', not 2.
The highest constant that all three terms have in common is a 2.

Text: these two triangles are similar

puteri [66]

Answer:

26.25 cm²

Step-by-step explanation:

The area of the shaded part is the area of the shaded triangle subtract the area of the white triangle.

Since the triangles are similar then the ratios of corresponding sides are equal.

let the height of the white triangle be h, then

$\frac{12}{9}$ = $\frac{10}{h}$ ( cross- multiply )
