Answer:
169
Step-by-step explanation:
13*13=169
We can split the two 13's up:
(10+3)(10+3)
Multiply 10 with 10, 10 with 3, 3 with 10, and 3 with 3.
Basically, just multiply every single term together.
100+30+30+9
100+69
169

The required equation is <u>135 + 9x > 250</u>.
The number of lawns Ed must mow is assumed to be x.
The amount Ed charges for each lawn he mows is $9.
Thus, the total amount Ed earns by mowing x lawns = $9x.
The savings which Ed has is $135.
Thus, the total amount Ed will have to spend can be written as the expression, $(135 + 9x).
The cost of the video game is given to be $250.
We are asked to write an equation, that can be used to find the number of lawns Ed mow, that is x so that the amount Ed has will be more than the amount he needs to buy the video game.
This can be shown as the equation:
Total amount Ed has > Cost of the video game,
or, 135 + 9x > 250.
Thus, the required equation is <u>135 + 9x > 250</u>.

Answer:
2x - 4
Step-by-step explanation:
Expand the brackets.
10x - 2(4x+5) + 6 = 10x - 8x - 10 + 6
Evaluate like terms.
10x - 8x - 10 + 6 = 2x - 4
Answer:
<h2>x=5</h2>
Step-by-step explanation:
Isolate by the x from one side of the equation.
First, you have to subtract by 3x from both sides.
Solve.
x=5
Therefore, the solution is x=5.
Answer:
3
Step-by-step explanation:
Volume if a cone is given by the formula
V=⅓πr²h
Where V is the volume, r is radius and h is height.
Given diameter as 3 m, the radius will be half of this hence 3/2=1.5 m
Substituting 4m for h and 1.5 m for r then
V=⅓π×1.5²×4=3π m³
Therefore, the missing figure is 3
