Answer:
AAA
Step-by-step explanation:
AAA is not a congruence theorem or postulate.
The last one: x/2=45; x = 90
the problem says: half of a number is 45.
let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45
to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides
x/2 • 2 = 45 • 2
x = 90
hope this helped!
Answer:
3 cm
Step-by-step explanation:
The formula for the area of a rectangle is ...
A = LW . . . . . . area is the product of length and width
Fill in the given values and solve for the width (W).
18 cm² = (6 cm)W
(18 cm²)/(6 cm) = W = (18/6) cm²/cm . . . . . . divide by the coefficient of W
W = 3 cm
The width of the rectangle is 3 cm.
