The <span>expression that represents n plus 7 multiplied by 3 is
(n + 7)(3)
The entire expression, (n + 7) is multiplied by 3 since it would be inconvenient to state the expression as given above if what is meant was
(n + 7x3). It would have simply been n plus 21.</span>
9/10 is the answer. Basic elementary math
Ax+bx−c=0
Step 1: Add c to both sides.
ax+bx−c+c=0+c
ax+bx=c
Step 2: Factor out variable x.
x(a+b)=c
Step 3: Divide both sides by a+b.
x(a+b)a+b=ca+b
x=ca+b
Answer:
69.66
Step-by-step explanation:
First you want to find the area of the square, which would be 121. ( 11 x 11 )
Next you want to find the area of the circle, 78.54 ((pi)5^2)
Last, you want to subtract the area of the circle, from the area of the square that is shaded. Youre left with 42.46
