11 + 3x = −15 − 4x
U subtract 11 from both sides 11+3x-11=-15-4x-11
Refine3x=-4x-26
Add 4x to both sides
3x+4x=-4x-26+4x
Refine7x=-26
Divide both sides by 7
<span>7x/7 = -26/7</span>
Refinex= -26/7
Answer:
the coefficient is 2
Step-by-step explanation:
Answer:
14 x 14 = 196
10 x 14 x 1/2(basically just dividing by 2) = 70
70 x 4(four sides of triangles) = 280
Now let's add the areas together:
196 + 280 = 476 cm^2 is your answer.
