Answer:
x = - 15
Step-by-step explanation:
Given
+ 3 = x - 2
Multiply through by 3 to clear the fraction
4x + 9 = 3x - 6 ( subtract 3x from both sides )
x + 9 = - 6 ( subtract 9 from both sides )
x = - 15
#1) 9=6 - 3 |4p + 9| now we're going to distribute
9= 6 - 12p - 27
9= 6 - 27 - 12p
9= - 21 - 12p
9 + 21= -12p
30= - 12p Now you are going to divide both side by -12
-12:30 = -12:-12p
-5/2= p final answer
#2) - |1 + 4a| = -13 now you going to change the sign
-1 - 4a = -13
-4a = -13 + 1
-4a = -12 now divide both side by -4
-4a:-4 = -12:-4
a = 3 final answer
If we collect like terms of the first equation, we can simplify to
2x - 8 = 180
If we add 8 to both sides, we get
2x = 188
And that means x = 94
If we substitute this into the second equation, we get
7(94) - 8 = ?
7 x 94 is equal to 658
658 - 8 = 650
Answer:
x = -15
Step-by-step explanation:
7 - 3x = -4(2+x)
7 - 3x = -8 -4x
7 + x = -8
x = -15
Answer:
Rectangular Prism → h = 2in
B = 143in
P = 48in
Surface Area = 382in²
Lateral Surface Area = 96in²
Triangular Prism → h = 7in
B = 20in
P = 27in
Surface Area = 229in²
Lateral Surface Area = 189in²
Triangular Prism → h = 10in
B = 120in
P = 60in
Surface Area = 840in²
Lateral Surface Area = 600in²
Step-by-step explanation:
Formulas: Total Surface Area = 2B = Ph
a²+b²=c²
Area =
bh
Lateral Area = Ph
