21)
a. -9 + (-12)
= - 9 - 12
= - 21
b. -17 + (3)
= -17 + 3
= - 14
c. 24 + ( -11 )
= 24 - 11
= 13
d. - 15 + (-10)
= - 15 - 10
= - 25
e. - 63 + ( -42) + 8
= - 63 - 42 + 8
= - 97
f. 101 + ( -11 ) + ( -100 )
= 101 -11 - 100
= - 10
Answer:
The answer is X=3/4 or -1/2
24.
This is because if we double the base and the height in the area equation it will raise any number by a factor of 4.
Answer:
Width is 10 1/2 inches and the length = 21 inches.
Step-by-step explanation:
Let the width be x then the length us 2x inches.
Perimeter = 2x + 2(2x) = 63
6x = 63
x = 10 1/2 inches.
