x - y = 3x + 6 is the simplified answer and is also correct

Step-by-step explanation:

The difference of x and y is the same as 3 times the sum of x and 2

Answer:

17) x = 10√2

18) x = 4√6

Step-by-step explanation:

These problems rely on your knowledge of the side ratios of special triangles

45°-45°-90° triangle: 1 : 1 : √2

30°-60°-90° triangle: 1 : √3 : 2

17) 5 is the short side of the isosceles right triangle, so its hypotenuse is 5√2. That length is the shortest side of the 30/60/90 triangle, so its longest side is 2 times that:

x = 10√2

18) 8 is the longest side of the 30/60/90 triangle, so its long leg will be 8(√3)/2 = 4√3. The hypotenuse of the isosceles right triangle is √2 times that, so ...

x = (4√3)(√2)

x = 4√6

Two step inequalities 5x-7_>8

Naddik [55]

Answer:

x ≥ 3

Step-by-step explanation:

5x - 7 ≥ 8

5x ≥ 8 + 7 (You take the common terms to one side)

5x ≥ 15

$\frac{5x}{5} \geq \frac{15}{5}$

x ≥ $\frac{15}{5}$

x ≥ 3

A cube has a surface area of 900 cm what is the number of cubic cm in the volume of the cube

Anna [14]

SA = 900cm^2
SA = 6×(s^2), where "s" is one side or edge of each square surface face
900 = 6s^2
150 = s^2
$\sqrt{150} = \sqrt{ {s}^{2} }$
$\sqrt{25} \times \sqrt{6} = s$
$5 \sqrt{6} = s$
So each side is
$5 \sqrt{6} \: cm \: long$
The volume (V) of a cube is:
$v = {s}^{3} = (5\sqrt{6})^{3} = {12.247}^{3} \\ = 1837 \: {cm}^{2}$
