Answer:
Answer is 4x² = 36
Step-by-step explanation:
Let that number be x:
[tex]4 \times x {}^{2} = 36 \\ {4x}^{2} = 36[/tex]
further more:
[tex] {x}^{2} = \frac{36}{4} [/tex]
take a square root:
[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{36}{4} } \\ \\ x = \frac{ \sqrt{36} }{ \sqrt{4} } \\ \\ x = \frac{6}{2} \\ \\ x = 3[/tex]
