Answers

Answer 1

Answer:

AB = 10

EF = 2

Step-by-step explanation:

to find the scale factor you have to divide the bigger scale by the smaller one which would be

(5x)/5 and 4/x

since both scale factors should be the same you can set them even to each other

(5x)/5=4/x

solve for x

(5x)/5=4/x

x=4/x

x^2=4

x=2

Answer 2

(5x)/5=4/x
x=4x
x^2=4
x=2

Answer: Answering all under step by step

Step-by-step explanation:

for a point just put a dot

for a line just draw a line with arrows pointing on both sides

for a line segment draw a line with two dots on the ends

for a ray draw a line with one side with an arrow and the other a dot

the difference between line and line segment is that a line is extended in both directions infinitely but a line segment has two endpoints

the difference between line segment and a ray is that a line segment has two endpoints and stops at the points while a ray goes on forever in one direction

for parallel lines just draw two lines on top of each other both going on forever

perpendicular line cross each other only once and never again. u can just make them look like a cross

How does the Distributive Property help when combining like terms to solve the equation 4x + 6x = 30?

Answers

Answer: it helps by making the question 10 times easier

Step-by-step explanation: because 4 and 6 both have the variable X they are like terms and can be added to each other unlike 30 it doesn’t have a variable meaning 4x or 6x cannot combine with 30 because it doesn’t have the variable X. Moving on 4x+6x is 10x as you add the number but X stays the same and so 10x=30 so you divided both sides by 10 because inverse operations and you get x=3 then after you import that into the question 4(3)+6(3)=30 which is the same as 12+18=30 which is true 30=30

Which quantity is greater than |–2.4|?
A. –6.3
B. –3
C. |–3.75|
D. |–1|

Answers

Answer:

C. |-3.75|

Step-by-step explanation:

You want to compare the given numbers to |-2.4|.

Absolute value

The absolute value of a number is its distance from zero on the number line. It is always positive.

Comparison

Here, we're comparing the answer choices to +2.4, and we want to find the one that is greater.

-6.3 < 2.4-3 < 2.4|-3.75| = 3.75 > 2.4 . . . . . this is the correct choice|-1| = 1 < 2.4

The quantity |-3.75| is greater than |-2.4|.

Answers

Answer:

168°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle, which is k, in this case.

m∠J = 78 and m∠L = 90° so the measure of exterior angle to ∠K:

78 + 90 = 168°

78 + 90 = 168 the exterior angle to

help me please i need so much help

Answers

Answer:

x=11

y=4

Step-by-step explanation:

To solve for x, the polygon is symmetrical (because it is regular). So x-3 = 8

x= 11

Similar means the sides are proportional (will be in a ratio)

Big polygon ~ small polygon

16 ~4

8~y/2

We can use these to solve for y.

[tex]\frac{16}{4} =\frac{8}{y-2}[/tex]

Cross multiply: 16y-32 = 32

y=4

The answer is pretty much X=11 y=4

Step-by-step explanation:

The correct option is B i.e., triangle RST ~ triangle UVW;5/6

Given,

In the Polygons,

In DRST, RS = 10 , RT = 15 and mDR = 32

In DUVW, UV = 12 , UW = 18 and mDU = 32.

To check the similarity and give the similarity ratio.

Now, According to the question:

Analysis the above given:

Here, RS/ UV = RT/UW = 5/6

AND, ∠R = ∠V = 32°

and, there is two sides are equal and one angle is equal.

Then, By postulate SAS two polygons are congruent.

Hence, The correct option is B i.e., triangle RST ~ triangle UVW;5/6
