Answer:
x = -2
Step-by-step explanation:
f(x) = -3x + 3
f(x) = 9
-3x + 3 = 9
Subtract 3 from both sides;
-3x = 6
Divide both sides by -3
x = -2
Answer:
10
Step-by-step explanation:
If the sides of the rectangle is 6cm and 8cm, then we mean that, the length and breadth are 6cm and 8cm
The diagonal which cross at AX will be the hypotenus of the triangle formed by drawing the diagonal.
Hence,
Hypotenus = sqrt (opposite² + adjacent²)
AX = sqrt[(8²) + (6²)]
AX = sqrt(64 + 36)
AX = sqrt(100)
AX = 10
