Determine whether each pair of figures is similar. If so, write the similarity statement and scale factor. If not, explain why. Number 1 and 2 on the second part.

Answers

9514 1404 393

Answer:

JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5

Step-by-step explanation:

We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.

1. JKLM ~ QRSP

JK : KL : LM : MJ = 20 : 15 : 24 : 25

QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)

The scale factor is 12/20 = 0.6.

2. ΔABC ~ ΔUVT

AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6

UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)

The scale factor is 24/16 = 1.5.

Answers

Answer: The given expression (3x − 5) − (4x + 6) = -x - 11.

Step-by-step explanation:

Given : Expression (3x − 5) − (4x + 6).

We have to simplify the given expression.

Consider the given expression (3x − 5) − (4x + 6).

Remove Parentheses ,

we have,

(3x − 5) − (4x + 6) = 3x - 5 - 4x -6

Combining like terms, we have,

LIKE TERMS are terms having same variable with same degree.

here 3x and -4x are like term and -5 and -6 are like terms,

Simplify, we have,

= 3x - 4x - 5 - 6

= -x - 11

Thus, the given expression (3x − 5) − (4x + 6) = -x - 11.

Use the Distributive Property to simplify the expression.
8(12+a)

Answers

[tex]\huge\boxed{\bf{Hi\:there!}}[/tex]

All we have to do to simplify this expression is multiply 8 by 12 and a:

8(12+a)

96+8a

That's our final answer.

[tex]\huge\boxed{\bold{Hope\:it\:helps!\:Good\:luck!}}[/tex]

[tex]\huge\mathfrak{LoveLastsAllEternity}[/tex]

The distributive property is defined as:

a x (b + c) = a x b + a x c

a x (b - c) = a x b - a x c

The final value of the expression 8 x (12 + a) after simplification using the distributive property is 96 + 8a.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

8(12 + a)

We will apply the distributive property.

The distributive property is defined as:

a x (b + c) = a x b + a x c

a x (b - c) = a x b - a x c

Now,

8 x (12 + a ) is in the form of a x (b + c)

So,

8 x (12 + a)

= 8 x 12 + 8 x a

= 96 + 8a

Thus,

The final value of the expression 8 x (12 + a) after simplification using the distributive property is 96 + 8a.

If y varies directly as x, and y = 7 when x = 3, find y when x = 7

Answers

Answer:

AStep-by-step explanation:

Direct variation, by definition, has the form shown below:

y=kx

Where k is the constant of proportionality.

Given the information in the problem, you can find k:

7=3k

k=7/3

Now you can find y when x=7 as following:

y=(7/3)x

Substitute values.

y=(7*7)/3

y=49/3
