Answer:
1)-5
2)-15
3)1
4)-11
5)-70
if negative use () for example
(-2)-7+4
Answer:
D
Step-by-step explanation:
From the triangle inequality, we know that the two small sides must be greater than the largest side. Let's let x be the third side:
However, 15 can also be our largest side. So:
Let's solve for x for both inequalities.
First inequality:
Add:
Flip:
Second inequality:
Subtract 7 from both sides:
So, we have the compound inequality:
Combine:
Our answer is D
And we're done!
Answer: 2.9525 or 3 if you round up.
Step-by-step explanation:
True. A rational number is a number that can be put into a fraction and all real numbers can in the form of x/1
A quadrilateral is a kite if the diagonals are:
i) perpendicular
ii) bisect each other
iii) not equal ( together with conditions i and ii this would make the quadrilateral a square)
Another definition of the kite is :
a quadrilateral with 2 pairs of equal adjacent sides.
Let's check the choices one by one:
A. <span>∠M is a right angle and MK bisects ∠LMJ.
according to these, ML and MJ may well be not equal...
</span><span>B. LM = JM = 3 and JK = LK = √17.
</span>
this makes the quadrilateral a kite.
<span>C. MK intersects LJ at its midpoint
</span>
if they are not perpendicular, the quadrilateral is not a kite.
<span>D. The slope of MK is –1 and the slope of LJ is 1.
this only means that MK and LJ are perpendicular, but not whether they bisect each other,
Answer: only B</span>
