The similarity ratio of STUV to CBED is 0.5

<h3>How to determine the similarity ratio of STUV to CBED?</h3>

For the shapes to have a similarity ratio, it means that:

The shapes are similar (not necessarily congruent)

From the diagram, the following sides are corresponding sides

ST and CB

Where

ST = 2

CB = 1

The similarity ratio of STUV to CBED is calculated as:

Ratio = CB/ST

Substitute the known values in the above equation

Ratio =1/2

Evaluate

Ratio = 0.5

Hence, the similarity ratio of STUV to CBED is 0.5

The perimeter of a triangle is 53 feet. One side of the triangle is 12 feet shorter than the second side. The third side is is 4

grandymaker [24]

Let the shortest side be = a, then side b = 2·a and side c = (b + 24)

We are given that a + b + c = 84

Substituting for b and c

a + 2·a + (a + 24) = 84

4·a + 24 = 84

4·a = 84 - 24 = 60

a = 60/4 = 15 feet

b = 2·15 = 30 feet

c = 15 + 24 = 39 feet

Express the area of the entire rectangle.

Cloud [144]

Answer:

$\huge\boxed{A=x^2+12x+35}$

Step-by-step explanation:

The formula of an area of a rectangle:

$A=lw$

l - length

w - width

We have

$l=x+7\\\\w=x+5$

Substitute:

$A=(x+7)(x+5)$

Use FOIL (a + b)(c + d) = ac + ad + bc + bd

$A=(x)(x)+(x)(5)+(7)(x)+(7)(5)\\\\A=x^2+5x+7x+35$

combine like terms

$A=x^2+(5x+7x)+35\\\\A=x^2+12x+35$

If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y ?

Reika [66]

Answer:

Step-by-step explanation:

2x - 3y = 24 ------ (1)

3x + 4y = 2 ------ (2)

(1) × 4,

8x - 12y = 96 ------ (3)

(2) × 3,

9x + 12y = 6 ------ (4)

(3) + (4)

17x = 96 + 6

= 102

x = 102 ÷ 17

= 6

Sub x = 6 into (2),

3(6) + 4y = 2

18 + 4y = 2

4y = 2 - 18

= -16

y = -16 ÷ 4

= -4

Therefore,

x - y = 6 - (-4)

= 6 + 4

= 10

i hope this helps you !!
