So...
ANS of
7(a)=(30)+(n x 20) {n=n. of hours}
7(b)= with my mind
Answer:
154
Step-by-step explanation:
The formula for the area is A=πr2
The line labeled 7 is the radium or the R in the formula
Replace 7 with R
A=π7(squared)
square seven
A=49π
pi is approximately 3.14
mutiply 7 by pi
A= 154
Answer:
A is TRUE (44 in²*2=88 in²)
B is FALSE x(x-3)=88 (the rectangle) or x(x-3)/2=44 (the triangle)
C is TRUE if x(x-3)=88==>x²-3x-88=0
D is TRUE :
x²-3x-88=0
Δ=9+4*88=361=19²
==>x= 11 or x=-8 (excluded for <0)
E is FALSE for 11*4≠88
