Answer:
x=6
Step-by-step explanation:
First you have to subtract 8 from 22 and you get -14. Then you rewrite the equation, 2x-14=-2.
Since your subtracting 14 you would add 14 to both sides, so -14+14 and -2+14. -2+14 will turn out to be 12 and then you divide 2 from both sides, so 2x-2 and 12-2.
Your answer will be x=6
Answer:
12 points
Step-by-step explanation:
9 is 1.5 times 6, so 8 times 1.5 gives you the answer of 12 points.
B. 3 √3
The shortcuts for a 30 60 90 triangle is that the:
Hypotenuse is 2 times the short leg
The long leg is √3 times the short leg.
Making it 3 √3
Another way is by the Pythagorean Theorem.
a^2+b^2=c^2
3^2+b^2=6^2
9+b^2=36
Subtract 9 from both sides
b^2=27
Square root both sides
b=5.2 or the √27
√27 can be simplified more
An equation that equals to 27 that has a perfect square is 9*3
√9* √3
The perfect square of 9 equals to 3
So 3 √3
Answer: 75
Step-by-step explanation:
when increased in scale,
both sides are multiplied by the factor which is 1.5.
72 =1.5(2L+2W)
