Answer:
(x + 7)(x + 3).
Step-by-step explanation:
x^2 +10x + 21
21 = 7 * 3 and 10 = 7 +3
so the factors are
(x + 7)(x + 3).
Answer:
g(5x)=0
Step-by-step explanation:
Given that g(x)=4
From the graph when x=-2 then g(x)=4
Hence 5x=-10
Now from the graph
g(-10)=0
Given:
The scale factor is 1:12.
Dimension of model = 32 cm
To find:
The actual dimension in m.
Solution:
Let x be the actual dimension.
The scale factor is 1:12 and the dimension of model is 32 cm.

On cross multiplication, we get


![[\because 1\ m=100\ cm]](https://tex.z-dn.net/?f=%5B%5Cbecause%201%5C%20m%3D100%5C%20cm%5D)
Therefore, the actual dimension is 3.84 m.
Answer:
e t
Step-by-step explanation:
Consider the given number is
in question as well as in options.
Given:
is considered as an irrational number.
To find:
The reason for given statement.
Solution:
We have,
When evaluated,
results in a nonterminating (infinite digits after decimal) and nonrepeating decimal, which is considered an irrational number.
Therefore, the correct option is C.
