− x + 16y

Step-by-step explanation:

2x + 5y − 3x + 11y

= 2x + 5y + − 3x + 11y

= 2x + 5y + − 3x + 11y

= (2x + − 3x) + (5y + 11y)

= − x + 16y

Answer:-6 $x^{12}$

Step-by-step explanation:

Open the brackets

-x is the same as -1x

(2 $x^{3}$ x - $x$ )(3 $x^{8}$ )

The bases will be multiplied while the powers will be multipled

-2 $x^{4}$ x 3 $x^{8}$

In the law of indices(multiplication), provided the bases are equal,they are to be added.

-6 $x^{4} +x^{8}$

= -6 $x^{12}$

I just need to check if the answer I got is right cause I’m not sure. (7th grade)

Answer:

48 ft.

Step-by-step explanation:

Since triangles ABC and DEC are similar (you can prove this quite easily), then we know the ratio of the sides are equal. This is a property of similar triangles. So we take the ratio of the sides CE and DE and the ratios of the sidesBC and AB.

We get:

$\frac{x}{40} = \frac{60}{50} \Rightarrow x = \frac{6}{5}\times 40 = 48.$

So x is 48 ft.
