Answer:

76.9 UNITS^2

Step-by-step explanation:

The area of the 14 by 15 rectangular shape is 210 square units, and

that of the semicircle is (1/2)(3.14)(7)^2, where 7 is half of the diameter (14).

(1/2)(3.14)(7)^2 = 76.9 UNITS^2

3/4√5-√3 + 2/4√5+√3 =b√3+a√5 find the value of b and a
Zielflug [23.3K]

Answer:

a = 5 / 4

b = 0

Step-by-step explanation:

3/4√5 - √3 + 2/4√5 + √3 = b√3 + a√5

3/4√5 + 2/4√5 + √3 - √3 = b√3 + a√5

5/4√5 + 0 = b√3 + a√5

0 + 5/4√5 = b√3 + a√5

b√3 = 0

b = 0 / √3

b = 0

a√5 = 5/4√5

a = 5/4√5 / √5

a = 5 / 4
