what is equivalent to (x+8)(x+4)?
1.x^2+12x32
2.2x^2+10x+12
3.2x^2+12x+16
Answer:
1. x^2+12x+32
Step-by-step explanation:
(x+8)(x+4)
x(x+4)+8(x+4)
x^2+4x+8x+32
x^2+12x+32
Answer:
x^2+12x + 32
Step-by-step explanation:
Lets solve this piece by piece
x * x = x^2
x*4 = 4x
8 * x = 8x
8*4 = 32
now if we add all of these we get
x^2 + 12x + 32
which happens to be the first option

A movie-theater employee notes an inverse relationship between the theater's popcorn sales
and its nacho sales. On a given night, the theater makes 990 from popcorn sales and
$1,892 from nacho sales. If on the next night the employees sell $1,452 of popcorn, how
much is earned from nachos?
Answer:
Nachos sale on next night = $ 2,776/-
Step-by-step explanation:
Data:-
On a given night theatre makes:
Popcorn sale = $990/-
Nacho Sales = $1,892/-
Next night Theatre makes:
Popcorn sale = $1,452/-
Nacho Sales = x (Let Assume)
Solution:
Given Night = Next Night
Popcorn sale/Nacho sale = Popcorn sale/Nacho sale
990 / 1,892 = 1,452 / x
0.523 = 1,452 / x
x = 1452 / 0.523
x = $2,776/-
How long is a string reaching from the top of a 13-ft pole to a point on the 3 points ground that is 7 ft from the base of the pole?
Answer:
14.76 ft
Step-by-step explanation:
L²= 13² + 7²
L² = 169 + 49 = 218
L = √218 = 14.76 ft
Answer:
14.8
Step-by-step explanation:
We use the Pythagoras theorem because the string and the pole are making a right angle triangle
7^2+13^2=c^2
49+169=c^2
218=c^2
14.8=c

The area of the circle is 452.39 mm².
What is the area of a circle ?The formula for the area of a circle
A = πr²
where r is the radius, half the diameter.
For the radius is 12 mm. Using that in the formula gives an area of ...
A = π(12 mm)² = 144 π mm²
For an appropriate value of π, the area is
144 π mm²
For 3.14 as the value of π, the area
144 (3.14) mm² = 452.39 mm²

A B and C from a triangle where BAC =90 AB = 7.4 mm and CA = 12 and find the length of AC , giving your answer rouned to 1DP
Question: A B and C form a triangle where BAC = 90°. AB = 7.4 mm and CA = 12 mm. Find the length of BC, giving your answer rounded to 1 DP.
Answer:
14.1 mm
Step-by-step explanation:
From the diagram attached,
Using pythagoras theorem,
a² = b²+c²............... Equation 1
From the attached file,
Given: a = x, b = 7.4 mm, c = 12 mm
Substitute these values into equation 1, and solve for x
x² = 7.4²+12²
x² = 54.76+144
x² = 198.76
x = √(198.76)
x = 14.1 mm
Hence, the length of BC = 14.1 mm
