1 answer:

Yes

But it must be a square since it has to follow the properties of both a rectangle and rhombus.

Also look to find the properties of them to verify yourself

If (x) = 3x^2 + 10, what is f(-7)

lara31 [8.8K]

Answer:

f(x) = -139

Step-by-step explanation:

f(x) = 3x^2 + 10 If f(-7)

f(-7)= 3 * -7^2 + 10

F(-7) = 3 * -49 + 10

f(-7) = -147 + 10

f(-7) = -139

Can someone show me the steps to solve this

saul85 [17]

Answer:

$87 - 18 \sqrt{6}$

Step-by-step explanation:

We want to expand:

$( \sqrt{6} - 9)^{2}$

We expand to get:

$( \sqrt{6} - 9)( \sqrt{6} - 9)$

$\sqrt{6} ( \sqrt{6} - 9) - 9( \sqrt{6} - 9)$

We expand using the distributive property to get:

$6 - 9 \sqrt{6} - 9 \sqrt{6} + 81$

$6 - 18 \sqrt{6} + 81$

Finally simplify to get:

$87- 18 \sqrt{6}$
