Answer:
D
Step-by-step explanation:
The diagonals of a rhombus intersect at right angles. So sneaky!!
So the third angle of the triangle containing the two base angles is 90 degrees.
- 2x + 3 + 3x + 2 + 90 = 180 Combine like terms
- 5x + 95 = 180 Subtract 95 from both sides
- 5x = 180 - 95 Combine the terms on the right.
- 5x = 85 Divide by 5
- x = 85/5
- x = 17
Answer:
2700 - 2000 = 700 - 100 = 600 - 200 = 400 - 100 = 300

Consecutive odd integers are 2 apart
they are
n,n+2,n+4
3(n²)=12+(n+2)(n+4)
expand
3n²=12+n²+6n+8
3n²=n²+6n+20
minus n² both sides
2n²=6n+20
divide bot sides by 2
n²=3n+10
minus 3n+10 both sides
n²-3n-10=0
factor
(n-5)(n+2)=0
n-5=0
n=5
n+2=0
n=-2
has to be odd, so no
n=5
n+2=7
n+4=9
the integers are 5,7,9
