Step-by-step explanation:

From the diagram we have
Base =
![4x+1](https://tex.z-dn.net/?f=4x%2B1)
Height =
![x+1](https://tex.z-dn.net/?f=x%2B1)
Area = Base × Height
126 =
![(4x+1)(x+1)](https://tex.z-dn.net/?f=%284x%2B1%29%28x%2B1%29)
⇒ Expand the double bracket
126 =
![4x^{2}+5x+1](https://tex.z-dn.net/?f=%204x%5E%7B2%7D%2B5x%2B1%20)
⇒ Subtract 126 both sides
0 =
![4x^{2}+5x-125](https://tex.z-dn.net/?f=%204x%5E%7B2%7D%2B5x-125%20)
⇒ Factorise the quadratic expression
0 =
![(x-5)(4x+25)](https://tex.z-dn.net/?f=%28x-5%29%284x%2B25%29)
⇒ Equating each factor to zero
![4x+25=0](https://tex.z-dn.net/?f=4x%2B25%3D0)
![x=- \frac{25}{4}](https://tex.z-dn.net/?f=x%3D-%20%5Cfrac%7B25%7D%7B4%7D%20)
We need the positive value of
![x](https://tex.z-dn.net/?f=x)
so we use
![x=5](https://tex.z-dn.net/?f=x%3D5)
Height = 5+1 = 6
Base = 4(5)+1 = 21

Answer:
x = 12
Step-by-step explanation:
Comparing corresponding sides of the 2 similar Δ 's inside the larger, then
=
( cross- multiply )
3x = 36 ( divide both sides by 3 )
x = 12
Answer:
10(q-3)
last option
please brainliest me btw
Step-by-step explanation:
The expression states 10q-30
The GCF is 10 (30 GCF by 10 Is 10)
Factor out 10
After, divide all the terms by 10
10 (10q/10) - 30/10
Simplify this and we get
10(q-3)
so in conclusion, it is the last option.
