A: no solution!

first, simplify each side of the equation.

3x + 5 - 10x simplifies to -7x + 5.
8 - 7x - 12 simplifies to -7x - 4.

then, add +7x on both sides of the equation to get the variable alone. if you add 7x to each side, you get left with 0.

so, that leaves 5 = -4 which is not true. so, that means there is no solution.

Answer to question one pleaseeeee help !!

Salsk061 [2.6K]

The answer is 19.6 cm^2

you should find the height of the triangle by heron formula: it will be 9.8

so the area is
$(9.8 \times 4 ) \div 2= 39.2 \div 2 = 19.6$

good luck
