45 POINTS !!!!

no bull, or i will report and get my points back

can someone accuracy work this out, they did not have geometry

Answer:

Sides = 8 each and base = 6

Step-by-step explanation:

Let congruent legs = x, then the base is x - 2 so,

P = x + x + (x - 2)

22 = 3x - 2

24 = 3x

8 = x (sides)

base = 8 - 2 = 6

Answer:

first option

Step-by-step explanation:

Using the rule of exponents

[tex](\frac{a^{m} }{a^{n} }) ^{p}[/tex] = [tex]\frac{a^{mp} }{a^{np} }[/tex] , then

[tex](\frac{2^{5} }{^{2} } )^{4}[/tex]

= [tex]\frac{2^{5(4)} }{3^{2(4)} }[/tex]

= [tex]\frac{2^{20} }{3^{8} }[/tex]

Answer:

z = 9

Answer:

D(1,4) - the fourth vertex, the area is equal to 12

Step-by-step explanation:

A(2,-1), B(1,0),C(4,3), They are consecutive, we need to find the point D, find the midpoint of AC (O)

xo= (xA+xc)/2    x0= (-2+4)/2=1

y0=(yA+yC)/2    y0= (1+3)/2=2

0(1,2)

O is the midpoint of BD, so let's find the vertex D

X0= (xB+xD)/2     1= (1+xD)/2   xD=1

y0= (yB+yD)/2      2= (0+yD)/2    yD=4

D(1,4)

the vector DA is (-2-1, 1-4)= (-3,-3)

the vector DC is (4-1, 3-4)= (3,-1)

The modul of DC is sqrt ((-3)^2+(-3)^2)= 3*sqrt2(the length of the side Dc)

The modul of DA is sqrt (3^2+(-1)^2)= sqrt10(the length of the side DA)

cosD= (-3*3+(-3)(-1))/3*sqrt2*sqrt10=-6/3*2*sqrt5=-1/sqrt5

sinD= sqrt (1- 1/5)=2/ sqrt5

S=3sqrt2*sqrt10*2/sqrt5= 12

Answer:

bro please help me make me brianliest I think c

Answer:

I don't believe any of these are correct.

I think the real order is:

-9/4, -1, [tex]\sqrt{6}[/tex], 1/4, 3.9

But I would choose D if I were you.

Answer: The side length is 3in (inches)

Step-by-step explanation:

Since it's a cube, all the sides are the same.

Formula for cube: L x W x H

= 3 x 3 x 3

= 27in

Answer:

h(-2) = 224

Step-by-step explanation:

Answer:

Lamar's next step is x^2 — 12x + 6 = 0

The solution to the equation is x = ± 6√30

Step-by-step explanation:

Answer:

c=sqrt21

Step-by-step explanation:

angle c is the angle between a and b, so use the cos law

c^2=a^2+b^2-2*a*b*cosC

c^2= 16+25-2*4*5*1/2

c^2=21

c=sqrt21

Answer:

1 : 14

hard to see image (try using screen shots)

but.... 2 inches to 4 feet would be

2 : 48 which is

1 : 14

Step-by-step explanation:

Answer:

formular 1/2 × base × height

1/2 × 2 × 8

16/2 = 8 ft

ans 8 ft

Answer:

Step-by-step explanation:

a = 2 ft ;   b = 8 ft ;  C = 91

[tex]Area = \dfrac{abSin \ C}{2}\\\\ =\dfrac{2*8*Sin \ 91}{2}\\\\=8* 0.99\\\\= 7.92\\\\= 8 \ ft^{2}[/tex]

Hope this helped!

Answer:

= -7/68

Step-by-step explanation:

1- first simplify the fractions in the bracket

= 3/8 (-17/8 7/12)

2- then calculate within the brackets

= 3/8 (-51/14)

3- lastly multiply & divide

3/8 (-51/14) = -7/68

Answer:

[tex]8 + x = 2 + 8 \\ 8 + x = 10 \\ x = 10- 8 \\ \\ x = 2 \\ then8 + 2 = 2 + 8 \\ thank \: you[/tex]

Answer:

2

Step-by-step explanation:

8 + 2 = 10, so basically, 10 - 8 = 2. Meaning the missing number to when 8 is added to something to equal 10, would be 2.

65 = m

Answer:

the balance is 56$

Step-by-step explanation:

its still 56$ because there isn't anything mention to tamara has buy something so he doesnt lose any money.

2.

[tex] area=\frac{1}{2} \times 6 \times 8 \\ = 24 [/tex]

3.

Answer:

x = 21

Step-by-step explanation:

72+46+(2x+20)=180

118+20+2x=180

138+2x=180

138-138+2x=180-138

2x=42

2x/2=42/2

x=21
