Answer:
No solutions
Step-by-step explanation:
2(x+1)=2x+5
Expand the parentheses:
2x+2=2x+5
Subtract 2x from both sides:
2=5
Since this is not true, this equation has no solutions. Hope this helps!

Answer:
Slope = 24.000/2.000 = 12.000
When y = 0 the value of x is 5/-12 the line therefore crosses the x axis at x=-0.41667
x-intercept = 5/-12 = -0.41667

Answer:
- 150.72 cm³
- 314 cm³
- 160 cm³
- 48 cm³
Step-by-step explanation:
Put the given numbers in the relevant formula and do the arithmetic.
<u>right cylinder</u>
V = πr²h = 3.14(4 cm)²(3 cm) = 3.14×48 cm³ = 150.72 cm³
<u>cone</u>
V = 1/3πr²h = 1/3(3.14)(5 cm)²(12 cm) = 3.14×100 cm³ = 314 cm³
<u>pyramid of unknown shape</u>
V = 1/3Bh = 1/3(16 cm²)(30 cm) = 160 cm³
<u>square pyramid</u>
V = 1/3s²h = 1/3(3 cm)²(16 cm) = 48 cm³
8(v−4)+7v=−2
(8)(v)+(8)(−4)+7v=−2
8v+−32+7v=−2
(8v+7v)+(−32)=−2
15v+−32=−2
15v−32=−2
Add 32 to both sides.
15v−32+32=−2+32
15v=30
Divide both sides by 15.
15v/15=30/15
v = 2
