A. If you're adding numbers with exponents with the same base, keep the same base and add the values of the exponents together.

3^2 * 3^4 = 3^(2+4) = 3^6

I don’t know how to find X or Y very urgent, need to figure this out how to solve plz help

Lena [83]

Answer:

x = 9

y = 9√3 = 15.6

Step-by-step explanation:

The triangle given is a right triangle, therefore:

✔️apply trigonometric ratio formula to find x:

Reference angle = 60°

Hypotenuse = 18

Adjacent = x

Thus:

Cos (60) = x/18

Multiply both sides by 18

18×cos(60) = x

9 = x

x = 9

✔️find y by applying pythagorean theorem:

y² = 18² - x² (pythagorean theorem)

y² = 18² - 9² (substitution)

y² = 243

y = √243

y = √(81*3)

y = 9√3 = 15.6

Ef is the median of trapezoid abcd (please explain the answer im so confused lol)

Art [367]

Step-by-step explanation:

Okay, so...

The Median of a trapezoid is directly in the middle. For some weird mathimatical reason you won't ever need to know unless it's on an exam or you become a math major, its midsegment is the average of the top length and the bottom length.

In other words,

EF = ( BC + AD ) / 2

So for part 1, we can use that equation to find x.

$EF = ( BC + AD ) / 2$

Insert known equations.

$4x-18=[(x+12)+(3x-4)]/2$

Simplify within parentheses.

$4x-18=[x+12+3x-4]/2$

$4x-18=[x+3x+12-4]/2$

Add.

$4x-18=[4x+8]/2$

Divide.

$4x-18=2x+4$

Simplify.

$(4x-2x) +(-18+18)=(2x-2x)+(4+18)$

$2x=22$

Divide both sides by 2.

$x=11$

Part 2 is a lot easier now. All we have to do is plug in 11 for x.

$BC =x+12$

$BC = 11+12$

$BC = 23$

$AD = 4x-18$

$AD = 4(11)-18$

$AD = 44-18$

$AD = 26$

$EF = 3x-4$

$EF = 3(11)-4$

$EF = 33-4$

$EF = 29$

Answer:

Part I: x = 11

Part II:

BC = 23
AD = 26
EF = 29

Farmer John looks out on his farm. One pen has chickens and pigs. John counted 12 heads and 34 legs. How many of each animal did

sasho [114]

34 legs and 12 heads

Chicken has 2 legs and Pig has 4 legs, both got one head

7 chicken heads, 7 x 2= 14 chicken legs

5 pig heads, 5 x 4= 20 pig legs

7 chicken heads + 5 pig heads = 12 heads

14 chicken legs + 20 pig legs = 34 legs

Answer: He saw 7 chickens and 5 pigs
