Answer:(-4,7.7)
Step-by-step explanation:
Answer:
15.5
Step-by-step explanation:
the r=1.9 h=4.1
Since the area of a triangle is hb*1/2, you do 2g^(2)h^(5)*<span>3gh, which is 6g^(3)h
^6. Then, you divide it by 2, which is 3g^(3)h^6.</span>
Answer:
¬(W∨S)→¬(J∨E)
D→(B∨C)
X is true
No
Step-by-step explanation:
The hypotheses "neither water nor soft drinks can quench your thirst" translates to ¬(W∨S) ("neither nor" negates the disjunction W∨S). The "if,... then" translates to the implication symbol (arrow). The conclusion "juice will not do it, unless the juice contains electrolytes" translates to ¬(J∨E). This is because if J or E were true, then J would be true (because E implies J), contrary to the conclusion that J is false ("juice will not do it"), then J∨S is false.
The hypothesis here is "the dyer breaks" hence D is the hypothesis. The conclusion is "we will hang the clothes to dry, or take the clothes to a coin-operated laundry" which is the same as (B∨C).
The proposition p→p is always true (according to truth tables). In this case, p:=X is true, then p is true and X is true.
X∨Y is false if and only if X is false and Y is false, so both statements X,Y must be false.
Answer:
All real numbers
Step-by-step explanation:
First, distribute the -4 on the left side
2x-4(x+2)=-2x-8
2x-4*x+-4*2=-2x-8
2x-4x-8= -2x-8
Combine like terms on the left side
-2x -8 = -2x -8
Since the two sides are equal, all real numbers are solutions
Hope this helps! :)
