A=(a+b/2) x h
a = 8
b = 14
h = 14
(8+14/2) x 14
(22/2) x 14
11 x 14 = 154
The answer is 154
Answer:
7
Step-by-step explanation:
a=2
b=2
c=1
2ab cos C=a²+b²-c²=2²+2²-1²=4+4-1=7
Answer:
Step-by-step explanation:
Price per pound of the walnuts = $ 6.50
Price of 4 pounds of the walnuts = 4 *6.50 = $ 26
Amount needs to be paid = Price of 4 pounds of walnut - coupon amount
= 26 - 3.75
= $ 22.25
Expression:
Cost to buy p pounds of walnuts = p * 6.50 = 6.5p
Cost to buy p pounds of walnuts, assuming at least one pound is purchased = 6.50 + 6.5p
-4,6
x^2 - 2x - 24 = 0
Factorise the equation
Products are -6 and 4
(x-6) (x+4) = 0
x = 6 and x = -4
