Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
Answer:
RP=190
TP=136
C=1,099
Step-by-step explanation:
RECTANGULAR PRISM, the equation is A=2(wl+hl+hw)
A=5*5+7*5+7*5
A=25+35+35
A=95*2
A=190
TRIANGULAR PRISM, the equation is A=1/2bh for the top and bottom triangles and A=lw for the sides
A=1/2(6)(4)
A=1/2*24
A=12
A=7*5
A=35
A=7*6
A=42
12*2=24
35*2=70
24+70+42=136
CYLINDER, the equation is A=2πrh+2πr2
A=2*3.14(7)(18)+2*3.14(7)^2
A=6.28*126+6.28*49
A=791.28+307.72
A=1,099
Answer:x=60
Step-by-step explanation:
110x+2400=100x+3000
-100x. -2400
10x= 600
X=60
The correct Option is (C) 5x(3x^2 + 4)
Explanation:
15x^3 + 20x
Take common terms out:
5x(3x^2 + 4) Which is option C.
Answer:
4w+10=-w
w=-2
Step-by-step explanation:
First, write out the equation in the algebraic form to make it easier to solve. This equation written out is 4w+10=-w. Then, isolate the variable and solve. Do this by subtracting 4w from both sides. Then, divide both sides by -5.
