217x+99=25
217x=25-99
217x= -74
X=-74/217

Answer:
C. 70 cm
Step-by-step explanation:
Split all the shapes, so, the square would be:
4 × 10 = 40
---------------------------------------------------------------------------------------------------------------
Each triangle has an area of 7.5:
7.5 × 4 = 30
---------------------------------------------------------------------------------------------------------------
30 + 40 = 70
---------------------------------------------------------------------------------------------------------------
Have a good day :)
Answer: x=-5 or x=2
Step-by-step explanation:
x^2+3x-10=0
x^2+5x-2x-10=0
x(x+5)-2(x+5)=0
(x+5)(x-2)=0
x+5=0 or x-2=0
x=-5 or x=2
