Answer:
B and D
Step-by-step explanation:
A difference of squares has the form a² - b²
4p² - 9 = (2p)² - 3² ← is a difference of squares
q² - 36 = q² - 6² ← is a difference of squares
Answer:
a) 26
b) 26/3
Step-by-step explanation:
a)
1) First, you have to turn 4 1/3 into an improper fraction, so you get 13/3
2) Then you do 13/3 *6/1 =78/3 (so you multiply both numerators and denominators)
3) Lastly, 78/3 can be simplified as 26
b)
1) First you turn both fractions into improper fractions, so you get 13/5 and 10/3
2) Then you do 13/5*10/3 (so you multiply both numerators and denominators)
3) You get 130/15, which can be simplified as 26/3
Answer:
p=1/2*3.14+d
1/2*3.14*19.5=30.615
=30.615+39
=69.615
=69.6
Step-by-step explanation:
since it's half a circle we take the formula of acricle to be half
