There's so many numbers in this one shape I'm confused ._.

The answer should be 12 units^2

starting from the left side of the shape you multiply base 2 by height 2 which gets 4 then divide by 2 since it is a triangle. next multiply 2x2 for the square in the middle which gets you 4. lastly multiply 6x2 for the triangle on the right which gets you 12 however bc it is a triangle you must divide by 2 and get 6. then add them all together and you get 12.

I GIVE BRAINLIEST PLEASE EXPLAIN What is the square root of 100???? BRAINLIEST

vovangra [49]

Every positive real number has TWOsquare roots; One is positive and one is negative. They are opposites of each other. 

10 is a square root of 100 because (10)(10) = 100, and ̶ 10 is also a square root of 100 because ( ̶ 10)( ̶ 10) = 100.

In general, “a” is a square root of “b” if a² = b, where “a” is a real number and b ≥ 0.

In conclusion:
 √(100) = 10 (the positive square root of 100) and 
 ̶ √(100) = ̶ (10) = ̶ 10 (the negative square root of 100)

Solve the proportion for x. 2/9=3/(x+2)

attashe74 [19]

Answer:

x as a fraction: 11 $\frac{1}{2}$

Step-by-step explanation:

Variable x cannot be equal to −2 since division by zero is not defined. Multiply both sides of the equation by 9(x+2), the least common multiple of 9,x+2.

2 ( x+ 2) = 9 x 3

Use the distributive property to multiply 2 by x + 2.

2x + 4 = 9 x 3

Multiply 9 and 3 to get 27.

2x + 4 = 27

Subtract 4 from both sides.

2x = 27 - 4

Subtract 4 from 27 to get 23.

2x = 23

Divide both sides by 2.

x = $\frac{23}{2}$

Simplify

11 $\frac{1}{2}$

Hope it helps and have a great day! =D
