The expression that can be formed by the given sentence is 8x² - 5.
What are expressions?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)So, for the expression as follows:
Eight and a number squared decreased by 5 can be:
Now, let the number be 'x'.
So, product of 8 and number squared: (8x²)Decreased by 5: (-5)Hence, the expression we obtain is:
8x² - 5
Therefore, the expression that can be formed by the given sentence is 8x² - 5.

A shopkeeper bought a fan for rupees 840 at what price should he sell it to make a profit of 10% If he makes a loss of 5% by selling at what is the selling price
Answer with Step-by-step explanation:
10% of 840 can be found by multiplying 840 by 0.10 (or dividing 840 by 10)
10% of 840 = 84
To make a profit of 84 he needs to sell at 840 + 84 = 924 rs
5% of 840 can be found by multiplying 840 by 0.05 (or dividing 840 by 20)
5% of 840 = 42
To make a loss of 42 he needs to sell at 840 - 42 = 798 rs

Jason multiplied 1.5 by a power of ten and got 150. What power of ten did he multiply by?
Answer:
Jason multiplied 1.5 by the whole number 10.
Step-by-step explanation:
As opposed to multiplying 1.5 by the tenth power, in which Jason would've received 57.66503..., he multiplied 1.5 by 10 units, resulting in a product of 150.
Hope this helps!
The power of ten did he multiply by 2.
Given that;
Jason multiplied 1.5 by a power of ten and got 150.
Let us assume that;
The value of power = x
Hence it can be written as,
1.5 × 10ˣ = 150
Divide both sides by 1.5;
10ˣ = 150/1.5
10ˣ = 100
It can be written as,
10ˣ = 10²
This gives,
x = 2
Therefore, the value of power is 2.

You are remodeling your kitchen. You have contacted 2 tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. Jim completed 1/2 the floor in 12 hours, Pete completed the other 1/2 in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what equation would you use to find the rate that Jim can lay tiles? Let x represent Jim's rate.
A. 10x = 12 (x -25)
B. 12x = 10 (x + 25)
C. 10x = 12 (x + 25)
D. 12x = 10 (x - 25)
Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.

Each face of a pyramid is an isosceles triangle with a 72 degree vertex angle. What are the measures of the base angles?
Answer:
52° and 52°
Step-by-step explanation:
An isosceles triangle has two base angles that are congruent. So let x be the measure of the base angle so that by Triangle Angle-Sum Theorem, we can write: X+X+76=180 and next would be 2X+76=180 and then it would be 2X=104 and finally it would be X=52. So there for the measures of the base angles are 52° and 52°. There hoped it helped!!!!

Identify the slope-intercept form and the graph of the line described by the equation 3x − 3y = 15.
Answer:
The slope-intercept form is y=x-5
The graph is in the picture below
Step-by-step explanation:
To find the slope-intercept you need to move y all by itself:
y=mx+b
subtract 3x on both sides:
-3y=-3x+15
Divide by -3 on both sides:
y=x-5
Hope this helps!
(Why I took two pictures is because to show you that the line is the same even with it being slop-intercept form)

Answer:
3rd option
Step-by-step explanation:
Substitute x = 0 into f(x) and check if the result is - 6
f(0) = (0 + 1)(0 + 2)(0 + 3) = 1 × 2 × 3 = 6 ≠ - 6
f(0) = (0 + 1)(0 - 2)(0 - 3) = 1 × - 2 × - 3 = 1 × 6 = 6 ≠ - 6
f(0) = (0 - 1)(0 + 2)(0 + 3) = - 1 × 2 × 3 = - 1 × 6 = - 6 ✔
Thus the 3rd option crosses the y- axis at (0, - 6 )

10x = 120
5x = 60
Step-by-step explanation:
paralellograms will become 360 degrees
so 2(5x) +2(10x)= 360
Simplify:
10x + 20x = 360
= 30x
divide both sides by 30 and isolate
30x = 360
30 30
x=12
multiply 12 by 10x and 5x
10x = 120
5x = 60

6x - 3y = 15
hint - subtract 6x, divide by -3, simplify
Answer:
y=2x-5
Step-by-step explanation:
1) Factor out the common term 3
3(2x-y)=15
2)Divide both sides by 3
2x-y=15/3
3) Simplify 15/3 to 5
2x-y=5
4) Subtract 2x from both sides
-y=5-2x
5) Multiply both sides by -1
y=-5+2x
6) regroup terms
y=2x-5

Angle 1=87°
Angle 2=88°
angle 1+2= 177
Step-by-step explanation:
I believe thsi should be right,
So angle 1 and 87° are the same because of some rule, then the angle above 2 would be 92 because of the same rule and its a straight line so 180-92=88 making angle 2, 88. When you add those it would be 177. Try that
