(a-b-2)(3a-3b-4) is your answer

Answer:

3(a-b)²-lo (a-b) +8

let (a-b) be x

3x²-10x+8

doing middle term factorization

3x²-6x-4x+8

3x(x-2)-4(x-2)

(x-2)(3x-4)

substituting value of x

(a-b-2)(3(a-b)-4)

(a-b-2)(3a-3b-4)

Answer:

  1) triangles are similar

Step-by-step explanation:

The height from vertex X of isosceles ∆WXY is 4 units. The width WY is also 4 units. In isosceles ∆UVW, the height from vertex V is 6 units, and the width UW is also 6 units.

The height ratios are ...

  ∆WXY/∆UVW = 4/6

The width ratios are ...

  ∆WXY/∆UVW = 4/6

The measures of ∆WXY are proportional to those of ∆UVW, so the triangles are similar.

_____

Strictly speaking, you cannot go by triangle height and width alone. That is why we made not of the fact that the triangles are <em>isosceles</em>. When base and height of an isosceles triangle are proportional, the Pythagorean theorem guarantees that side lengths are proportional. Trigonometry can also be invoked to support the claim that angles are congruent.

What is the expression of 4 +34times7
Harrizon [31]

Answer:

Instead of times you should use * to represent multiplication.

So, the expression is 4 + 34*7

We follow PEMDAS,

So first we multiply,

4 + 238

Now we add.

Choose the letter of the correct answer (Complete the congruence statement)
rewona [7]

Answer:

D

Step-by-step explanation:

when flipping and turning the second triangle, so that it is oriented as the first triangle (we see DE corresponds to AB - consider at what corner point the right angle is : at A and at D; DF corresponds to AC, EF corresponds to BC), we see immediately that BCA is the same sequence of corners as the corresponding EFD.
