The longest side of a triangle is 10 cm which group of the line segments could form the other two sides of the triangle 5 cm and 5 cm

7 cm and 8 cm

9 cm and 10 cm

4 cm and 4cm​

7 cm and 8 c

Step-by-step explanation:

7 cm and 8 cm.  Why?  Because both are shorter than the longest side (10 cm) but add up to more than 10 cm.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
