Answer:
2x + 15 = -23
x = -19
Step-by-step explanation:
2x + 15 = -23
2x+ 15-15 = -23 -15
2x = -38
2/2x = -38/2
x = -19
Answer:
The missing area for both sides is 48ft²
the missing dimension is 12ft
Step-by-step explanation:
Add all the areas up
12+36+12+36=96
192-96=96
96÷2=48
48÷4=12
An easy way to find this is to look at the cross section, and see where the lines meet
The error would be assuming the altitude is a bisector and divides the sides evenly.
Answer: -6
Step-by-step explanation:
9% = .09
.09-6.375 = −6.285
6.285 = 6.285/1 = 62.85/10 = 628.5/100 = 6285/1000
GCF = 5, 1257/200 = 6
-6
-6.285 = -6
