Answer: x = 9/4
Step-by-step explanation:
4x+12+2=23
4x+14 = 23
4x = 9
x = 9/4
Not 100 % but I would think as likely as not because you have the same amount of both. 1/2 the chance
Recall that A = 1/2bh.
We are given that h = 4+2b
So, putting it all together:
168 = 1/2 b(4+2b)
168 = 1/2(4b + 2b^2)
168 = 2b + b^2
b^2 + 2b - 168 = 0.
Something that multiplies to -168 and adds to 2? There's a trick to this.
Notice 13^2 = 169. So, it's more than likely in the middle of the two numbers we're trying to find. So let's try 12 and 14. Yep. 12 x 14 = 168. So this factors into (b+14)(b-12) So b = -14 or b =12. Is it possible to have a negative length on a base? No. So 12 must be our answer.
Let's check this. If 12 is our base, then according to our problem, 2*12 + 4 would be our height... or 28. so what is 12 * 28 /2?
196. Check.
Hope this helped!
First we would need to find the portion of the gymnasium to the blueprint to do that please do this:
88/5.5 = 16
The length divided by the blueprint's length
Since we know that the gymnasium is 16 times the blueprint, to find the width divide 16 to 76:
76/16 = 4.75
The width divided by the 16 times
The width of the blueprint is 4.75 inches
There is no picture or instructions. what do u need
