Step-by-step explanation:
first number=x
second number=x+2
third number=x+4
(x+2)(x+4)=3x+26
x(x+4)+2(x+4)=3x+26
x²+4x+2x+8=3x+26
x²+6x+8=3x+26
x²+6x-3x=26-8
x²+3x=18
x²+3x-18=0
you can use that to find the numbers
Answer:
For question 2 (Triangle):
The triangle hThe entire triangle area = 2 * 13.125 =
26.25
Triangle perimeter both legs = 16.6 + base (7) = 23.6
For question 1 (Parallelogram):
longer congruent sides = 6-0 OR 4-(-2) = 6units
area= 3×6 = 18units^2
X=3. 33x-21x equals 12x. 24+12=36. 12x divided by 36 equals 3
2 × 8 = 16
16 + 7 = 21
so its 21/8
Answer:
