Answer:

$\sqrt{5}$

Step-by-step explanation:

distance between two points:

$d = \sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}$

we have:

(6, -2), (8, -3)

$x_{1} = 6$

$y_{1} =-2$

$x_{2} = 8$

$y_{2} =-3$

so we have:

$d =\sqrt{(8-6)^{2}+ (-3-(-2))^{2}}\\\\d =\sqrt{(2)^{2}+ (-1)^{2}}\\\\d = \sqrt{4+ 1}\\\\d=\sqrt{5}$

Geometry Question- Triangles

xz_007 [3.2K]

The answer is D) 1/4

We draw the triangle and we notice triangle ABC is similar to DBE so all the sides will be in proportion.

Since AC is 4 times longer than DE, all the sides of triangle ABC will be 4 times longer.

Then if the perimeter of ABC was lets say 8, DBE would have a perimeter of 2.

D is the answer :)

Does anyone know what I am missing to get the final mark? Any ideas would be much appreciated :)

Law Incorporation [45]

Answer: Isosceles

<u>Step-by-step explanation:</u>

Given: AB || DE , BC is a transversal

∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°

∠DCA, ∠ACB, & ∠BCA are supplementary --> ∠ACB = 50°

By the Triangle Sum Theorem, ∠A+∠B+∠C = 180° --> ∠CAB = 50°

Triangle is isosceles because ∠A ≅ ∠C

Find two consecutive integers such that the sum of the greatest integer and twice the lesser integer is 40.

ziro4ka [17]

Answer:

13 and 14.

Step-by-step explanation:

So we have two consecutive integers.

Let's call the first integer a.

Since the integers are consecutive, the other integer must be (a+1) (one more than the last one).

We know that the sum of the greatest integer (or a+1) and twice the lesser integer (a) is 40. Therefore, we can write the following equation:

$(a+1)+2(a)=40$

The first term represents the greatest integer. The second term represents 2 times the lesser integer. And together, they equal 40.

Solve for a. Combine like terms:

$a+1+2a=40\\3a+1=40$

Subtract 1 from both sides. The 1s on the left cancel:

$(3a+1)-1=(40)-1\\3a=39$

Divide both sides by 3:

$\frac{3a}{3}=\frac{39}{3}\\a=13$

Therefore, a or the first integer is 13.

And the second integer is 14.

And we can check:

14+2(13)=14+26=40
