How do you solve this question and what’s the answer

shutvik [7]

Answer:

7.74 square cm

Step-by-step explanation:

To find the leftovers, calculate the area of the square and the area of the circle. Then subtract the two.

Square: A = s*s = 6*6 = 36

Circle: $A = \pi r^2\\A = \pi 3^2\\A = 9 \pi\\A= 28.26$

The area leftover is A = 36 - 28.26 = 7.74

What is 7 times the sum of a squared and b minus 4 times the sum of a squared and b

spayn [35]

The sum of a squared and b is given by
$a^2+b$

7 times the sum of a squared and b is given by
 $7(a^2+b)$
while 4 times the sum of a squared and b is given by
 $4(a^2+b)$

Therefore, 7 times the sum of a squared and b minus 4 times the sum of a squared and b is given by

$7(a^2+b)-4(a^2+b)=3(a^2+b)$
