Answer:

24+2x+2y

B) 122 units² if the missing measurement is 7.

Step-by-step explanation:

12+12+x+x+y+y=24+2x+2y

The surface area cannot be determined with just a number and no variables because there is a missing measurement.

The missing measurement looks a lot like 7 so let's assume it's 7

12+12+21+21+28+28=122 units²

Hello!

Answer: ⇒⇒⇒⇒⇒⇒⇒ =54

_________________________________________________________________

Step-by-step explanation:

First you had to convert element to fraction.

$\frac{2}{3}*\frac{81}{1}$

Then you had to cross out by the common factor of 3.

$\frac{2}{1}=\frac{27}{1}$

Multiply by the fraction.

$\frac{2*27}{1*1}$

Multiply by the number.

$2*27=54$

$=\frac{54}{1*1}$

Again multiply by the number.

$1*1=1$

$=\frac{54}{1}$

Apply rule.

$\frac{54}{1}=54$

54 is the right answer.

WILL GIVE BRAINLIEST What is the value of x in the figure? 1042 (3x – 19)

Anna11 [10]

Answer:

x = 41

Step-by-step explanation:

We know these angles will be equal to each other (they are across from each other, I honestly forget the term ) so we can set up an equation

Our equation from given: 104 = 3x - 19

Adding 19 to both sides 123 = 3x

Dividing both sides by 3: 41 = x

Answer: x = 41
