Answer: x=-1.9
Step-by-step explanation:


-18 on both sides

divide 7 on both sides

Consider two <u>right triangles</u>:
1. ΔABC with <u>vertices</u> A(0,0), B(0,2), C(6,0). Then AB is perpendicular to AC and AB=2 units (<u>vertical leg</u>), AC=6 units (<u>horizontal leg</u>).
2. ΔXYZ with vertices X(6,-10), Y(6,0), Z(36,-10). Then XY is perpendicular to XZ and XY=10 units (vrrtical leg), XZ=30 units (horizontal leg).
The equation of the line BC is

Check whether points Y and Z lie on this line:
Y(6,0):
- true;
Z(36,-10):
- true.
Answer: the hypotenuses of these two triangles could lie along the same line
Answer:
Ans = 1980
Step-by-step explanation:
(10 x 100 ) + 980 = (1000) + 980
therefore
1980 is the answer
