As <GNJ & < JNK form a striaght angle
And < JNK = 90°
So <GNJ = 90°
So <GNH + <HNJ = 90°
So GNH & HNJ are complimentary is true.
As JNK and KNL do not form a straight angle.
So <JNK +< KNL is not equal to 180°.
Hence JNK and KNL are supplementary is not true.
As <KNM & < JNK form a straight angle
And < JNK = 90°
So <KNM = 90°
So <KNL + <LNM = 90°
So KNL & LNM are complimentary is true.
As HNL makes a straight angle
And so
mHNK + mKNL = 180° is true
As MNG itself is 90°
So
<MNG + <GNH cannot be 90° hence this is false.

I think this is what you mean by simplest fom
Kenny can buy 15 t shirts and 3 sweatshirts.
Step-by-step explanation:
Given,
Number of members = 18
Cost of each t shirt = $9
Cost of each sweatshirt = $15
Money = $180
Let,
x be the number of t shirts
y be the number of sweatshirts
According to given statement;
x+y=18 Eqn 1
9x+15y=180 Eqn 2
Multiplying Eqn 1 by 9
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 6
Putting y=3 in Eqn 1
Kenny can buy 15 t shirts and 3 sweatshirts.

Answer:
-19
Step-by-step explanation:
I see "2^2-3/4d+1/8=0." I think you meant "<span>2x^2-(3/4)d+(1/8)=0." If this is correct, then simplify
</span>2x^2-(3/4)d+(1/8)=0 by mult. every term by the LCD, which is 8:
16d2 - 6d + 1 = 0
Using the quadratic formula, I obtained:
6 plus or minus sqrt(6^2 - 4(16)(1) )
d = --------------------------------------------------
2(2)
Before you do anything else, ensure that you have copied down this problem completely and correctly. Was that 2^2 or was it 2d^2? ???
