Is 36z^2 - 9 a difference of squares?

Mathematics
1 answer:
Dvinal [7]3 years ago
4 0

Answer:

yes

Step-by-step explanation:

A difference of squares has the form a² - b² = (a - b)(a + b)

note that 36z² = (6z)² ⇒ a = 6z and 9 = 3² ⇒ b = 3

36z² - 9 is a difference of squares and factors as (6z - 3)(6z + 3)

Anon25 [30]

Answer:

129

Step-by-step explanation:

Collinear means that the points X, Y, and Z are on the same line. The question asks for one possible value of YZ, so for this, let's assume point X is between Point Y and Point Z.

This means...

XY+XZ=YZ

54+75=YZ

Please answer this correctly without making mistakes
Monica [59]

Answer:

g=56

Step-by-step explanation:

In similar shapes, corresponding sides are always in the same ratio.

For example,

if the sides in triangle 1 were a and b, and triangle 2 had side lengths c and d, c and a had the same ratios, and b and d had the same ratios

and triangle 1 was similar to triangle 2, the ratio between the sides of the triangles would be

a/c, which is also equal to b/d

What that means is that in this situation, 8/5=g/35.

8/5=g/35

Cross multiply.

(8)*(35)=g*(5)

280=5g

g=56
