Answer:

Yes, the shapes are similar. Note, the angles are equivalent and the sides are scales of each other satisfying the requirements for similarly.

Step-by-step explanation:

For a shape to be similar there are two conditions that must be met. (1) Must have equivalent angles (2) Sides must be related by a scalar.

In the two triangles presented, the first condition is met since each triangle has three angles, 90-53-37.

To test if the sides are scalar, each side must be related to a corresponding side of the other triangle with the same scalar.

9/6 = 3/2

12/8 = 3/2

15/10 = 3/2

Alternatively:

6/9 = 2/3

8/12 = 2/3

10/15 = 2/3

Since the relationship of the sides is the scalar 3/2 (Alternatively 2/3), then we can say the triangles meet the second condition.

Given that both conditions are satisfied, then we can say these triangles are similar.

Note, this is a "special case" right triangle commonly referred to as a 3-4-5 right triangle.

Cheers.

Factor the polynomial by grouping : x^3+5x^2-6x-30
andrew-mc [135]

The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.

x^3+5x^2-6x-30

(x^3+5x^2)+(-6x-30)

x^2(x+5)+(-6x-30)

x^2(x+5)-6(x+5)

(x^2-6)(x+5)

-------------

Answer: (x^2-6)(x+5)

You might need a maths degree for this one, I believe it’s 4 but don’t quote me on that.

Joe is 3 times as old as Pepe In how many years will Joe be only twice as old as Pepe ? How old are they now? How old will they
antoniya [11.8K]
Let x = Wally's age now

Then, 3x = Jose's age now

Wally's age 5 years from now = x+5

Jose's age 5 years from now = 3x+5

(x+5) + (3x+5) = 42

4x + 10 = 42

4x = 32 x = 8

Wally is 8 years old and Jose is 24.
