Answer:
3a+7b>2b-8b
3a>2b-8b-7b
3a>2b-15b
3a>-13b
a>-13b/3
Step-by-step explanation:
True because a triangle must have 3 angles that add up to 180 degrees and, since a right angle is 90 degrees, it cannot have 2 right angles
Answer:
x=2(twice)
y=0(twice)
Step-by-step explanation:
This question can be solved using substitution method
So let's solve
y=x+2....(1)
y=x2+5x+6....(2)
Substitute (1) into(2)
X+2=x2+5x+6
Collect like terms
X2+5x-x+6-2=0
X2+4x+4=0
X2+2x+2x+4=0
X(x+2)+2(x+2)=0
(X+2)(x+2)=0
X+2=0
Substrate 2 from both sides
X=-2
X+2=0
X=-2
Let's substitute the value of x into (1)
y=x+2
y=-2+2
Y=0(twice)
Answer:
JK = 30 .
Step-by-step explanation:
As JMLK is a kite the diagonals bisect each other at right angles so triangle JNK is a right triangle.
JK^2 = 18^2 + 24^2 = 900
JK = 30.
