Answer:
Step-by-step explanation:
32 x 10 = 320
32 x 4 = 128
320 + 128 = 448
Put -4 in place of x

Answer:
(B)
Step-by-step explanation:
First, we determine the height of the triangle which we label as y.
Using Pythagoras Theorem.

In the smaller right triangle with hypotenuse, x
Base = 7-3 =4 Units
Height, y= 24 Units
Therefore, applying Pythagoras Theorem.:
