To find that out, we must find out how much larger <DEF is than <ABC
So we take the sides DE and divide it by AB
4.5/3=1.5
That means <DEF is 1.5 times larger than <ABC
So now, we take BC, and multiply it by 1.5
2 x 1.5 = 3
So EF=3

Answer:
22
Step-by-step explanation:
(3+8)2
You solve what is in the parenthesis first, getting 11.
(11)2
When a number is next to parentheis with no sign (+, -), you multiply.
You then multiply 11 and 2, and get 22.
- Multiply by the conjugate ![\frac{4+ \sqrt{3} }{4+ \sqrt{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2B%20%5Csqrt%7B3%7D%20%7D%7B4%2B%20%5Csqrt%7B3%7D%7D)
= ![\frac{5(4+\sqrt{3})}{(4-\sqrt{3})(4+\sqrt{3})}](https://tex.z-dn.net/?f=%5Cfrac%7B5%284%2B%5Csqrt%7B3%7D%29%7D%7B%284-%5Csqrt%7B3%7D%29%284%2B%5Csqrt%7B3%7D%29%7D)
![(4-\sqrt{3})(4+\sqrt{3})=13](https://tex.z-dn.net/?f=%284-%5Csqrt%7B3%7D%29%284%2B%5Csqrt%7B3%7D%29%3D13)
= ![\frac{5(4+\sqrt{3})}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B5%284%2B%5Csqrt%7B3%7D%29%7D%7B13%7D)
Answer:
X = -20
Step-by-step explanation:
X = -2(6+4)
^ add 6 and 4 together first because they are in parentheses
-2(10)
^ this parenthesis means you want to multiply -2 and 10
because 2 x 10 = 20
that must mean -2 x 10 = -20
therefore, the value of X is -20
X= -20
