Given:
square based pyramid = 3.5 cm base
side length = 7 cm
Base Area = (3.5cm)² = 12.25cm²
Surface Area = Base Area + 2sl = 12.25cm² + (2 * 3.5cm* 7cm)
S.A = 12.25 cm² + 49 cm²
<span>S.A = 61.25 cm² </span>

Answer:
can be expressed in nested form as 
Step-by-step explanation:
Considering the polynomial

Expressing the polynomial by nesting
So,

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

Step 3) Repeating the previous step until all terms are within the equation.
So,

Therefore,
can be expressed in nested form as

Answer:
x = 2 and y =
Step-by-step explanation:
y = 2x - 1
y = -x + 5
2x - 1 = -x + 5
2x + x = 5 + 1
3x = 6
x = 6/3
x = 2
y = 2(3)-1
y = 5
