Answer:

4

Step-by-step explanation:

The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.

Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:\frac{x}{x + 12} = \frac{x + 1}{x + 16} **

We now multiply both sides of the above equation by (x + 12)(x + 16) to get: x(x + 16) = (x + 1)(x + 12)

x^{2}  + 16x = x^{2}  + 13x + 12

3x = 12

x = 4

That means our answer, for the value of x, is 4

** Make sure you don't say \frac{x}{12} = \frac{x + 1}{15}, because those aren't the sides of the larger square.

Answer:

x=4

Step-by-step explanation:

By the Triangle Proportionality Theorem:

\displaystyle \frac{x}{12}=\frac{x+1}{15}

By cross-multiplication:

\displaystyle 12(x+1)=15(x)

Distribute:

12x+12=15x

Subtract 12x from both sides:

12=3x

Hence:

x=4

Find the answer given below​
Anastasy [175]

Answer:

Surface area = 6l^2

Volume = l^3

If total surface area increased by 2, then the length increased by \sqrt{2}

Volume then is increased by (\sqrt{2}l)^3 = 2\sqrt{2}l^3

1 :2 \sqrt{2}

Which is not an option in the question so this question clearly has a problem.

First of all It's supposed to be "then" not "than," so I'm not sure who teaches math without even knowing this basic grammar.

Second of all, if the answer is 8:1 the question should be "If <u>each sides</u> of a cube is doubled" not "the lateral surface area." Come to think of it what even is lateral surface area of a cube if all sides of the cube is supposed to be same.

Or, if the answer is 2:1 then, it should be If height lateral surface area of a cube is doubled <u>by doubling the height and without changing the length and width</u>"  But, then the the shape would no longer be a cube.

Who even wrote this garbage question what.
