Answer:
(-7)*(-8)
Step-by-step explanation:
Two negatives make a postive so 7*8=56 and 4*6=24.
1.-34+24=10
2. 56-100=44
3.-5×-9=45
4.-27/9=3
5.243/(-3)=21
6.45×-13= 585
7.8-12=9
8.-20+(-20)=40
9.3-(-7)= 10
10.31×-5=155
11.1000/(-10)=100
12.-2×0=0
13.25-24=1
14.24+40= 64
15.6+(-9)=3
16.-63/7=9
17.-50×-20=1000
18.-7×-8=18
19.9-(-10)=19
20.0×-100=0
408.3%
the answer is D
B. 20x + 15
Get rid of the parenthesis and combine like terms: 18x + 2x and 9k + 6k
You get: 20x + 15.
