Perimeter of a square: side length * 4, since squares have equal side lengths
Take 2x - 3 for the side length and plug it into the formula.
(2x - 3) * 4 can be rewritten as 4(2x - 3)
Distribute 4 inside the parentheses.
8x - 12 = perimeter of the square
Answer:
<em>JM = 5 mm </em>
Step-by-step explanation:
Δ JMK is the right angled triangle ⇒ JM² = JK² + KM²
JM² = 3² + 4²
<em>JM = 5 mm</em>
Answer: 100
Step-by-step explanation:
Sub in 5 for b in the expression

You must do the exponent first as it comes before multiplication in the order of operations

Now multiply

Answer:
n (aub)= n (a)+ n(b)
n (anb) = n (a)-n (b)
only a= n(a)+n(b) -(aub)
n only b= n (a)+n (b)-n (anb)
now solve your self because this formula help to solve
