What inequality represents the sentence? The product of a number and 12 is no more than 15.

bulgar [2K]

So when this sign < has a line under the greater sign so this mean greater or equal

same with this

12>= x so this mean 12 greater or equal x but than there is a line under the greater sign so this mean equalitie sure too

hope this will help you

Expand.<br> If necessary, combine like terms.<br> (X+ 6)(x+6)=

lapo4ka [179]

Answer:

Step-by-step explanation:

Use FOIL method

(x + 6)(x +6) = x*x + x*6 +6*x + 6*6

= x² +<u> 6x + 6x</u> + 36 {add like terms}

= x² + 12x + 36

Find the value of x in the isosceles triangle shown below.

guajiro [1.7K]

Answer:

B) $x = \sqrt{60}$

Step-by-step explanation:

1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.

2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: $a^2 + b^2 = c^2$ , where a = height, b = base, and c= hypotenuse.

$a^2 + 2^2 = 8^2$
$a^2 + (2*2) = (8*8)$
$a^2 + 4 = 64$ (Simplify both sides of the equation)
$a^2 + 4 - 4 = 64 - 4$ (Subtract 4 from both sides)
$a^2 = 60$
$\sqrt{a^2} = \sqrt{60}$ (Take square root of both sides
$a = \sqrt{60}$

3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.
