Write an equivalent expression. -2(7+5g)
Answer:
-2(7) + -2(5g)
Step-by-step explanation:
Using the distributive property we can confirm that:
-2(7) + -2(5g) = -2(7+5g)
Answer:
−14−10g
Step-by-step explanation:
First, solve the product:
-2 ⋅ 7 - 2 ⋅ 5g
Multiply -2 times 7 to -14.
So, the equivalent expression would be:
-14 - 2 ⋅ 5g = -14 - 10g
-14 - 10g

Choose the three equivalent expressions: (Select all that apply 6( 4x + 5y) 20x + 30y 2(10x + 3y) 10(2x) + 10( 3y) 10(2x + 3y)
Answer
Option 2, 4 and 5 :)
Step-by-step explanation:
Option 2 is already simplified to 20x + 30y
Option 4,
10*2x=20x and 10*3y= 30y so option 4 also simplifies to 20x + 30y
Next Option 5, 10*2x= 20x and 10*3y=30y. So it's also 20x + 30y
A circular decorative wall hanging was radius of 6 inches which measurement is closest to the area of the wall hanging in square inches
Answer:
28.270
Step-by-step explanation:
Multiply Pi (3.1416) with the square of the radius (r) 2. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Calculated out this gives an area of 28.2744 Square Inches. that would be your formula wright it down this is how u get your answer

5. Suppose you invested PHP 25,000 at a simple interest at a rate of 2.5%, how much will be your investment after
10 years? a. PHP 43,750.00
C.PHP 45,730.00
b. PHP 31,250.00
d. PHP 47,350
Answer:
b. PHP 31,250.00
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = PHP 25,000
Rate = 2.5%
Time = 10 years
Simple interest = principal × rate × time
= PHP 25,000 × 2.5% × 10
= 25,000 × 0.025 × 10
= 6,250
Simple interest = PHP 6,250
Investment after 10 years = principal + simple interest
= PHP 25,000 + PHP 6,250
= PHP 31,250
Investment after 10 years = PHP 31,250

The cylinder has a height of 30 cm and a radius of 11 cm. Work out the total surface area of
the cylinder. Give your answer correct to 2 significant figures.
Answer:
[tex]A=2833.71\ cm^2[/tex]
Step-by-step explanation:
Given that,
The height of the cylinder, h = 30 cm
The radius of the cylinder, r = 11 cm
We need to find the total surface area of the cylinder. The formula for the total surface area of the cylinder is given by :
[tex]A=2\pi rh+2\pi r^2\\\\A=2\pi \times 11\times 30+2\pi \times (11)^2\\\\A=2833.71\ cm^2[/tex]
So, the total surface area of the cylinder is [tex]2833.71\ cm^2[/tex].

Which best represents an equation to solve for x?
3x = 75
3x +75 = 90
3x + 75 + 90 = 180
3x + 75 +90 = 360
Answer:
3x + 75 + 90 = 180
x = 5°
Step-by-step explanation:
3x + 75° + 90° = 180°( being sum of angles of triangle)
3x = 180° - 75°- 90°
3x = 15°
x = 15° / 3
x = 5°

The equivalent value of the expressions are solved by the exponents
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
A = 25ˣ
On simplifying , we get
A = ( 5 . 5 )ˣ
A = ( 25 )ˣ
And , A = 5ˣ . 5ˣ
From the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
A = 5²ˣ
A = 25ˣ
Hence , the expressions are ( 5 . 5 )ˣ = 5²ˣ = 5ˣ . 5ˣ = 25ˣ

Manny needs to solve the equation x2 – 8x – 24 = 0 by completing the square. Which pair of steps is the most efficient way to begin?
Answer:
B
Step-by-step explanation:
So for some reason the person didn't put the equations... I had the same question so here they are.
A.x^2 – 8x = 24
x2 – 8x + 4 = 24 + 4
B.x^2 – 8x = 24
x2 – 8x + 16 = 24 + 16
C.x^2 – 8x = 24
x2 – 8x + 64 = 24 + 64
D.x^2 – 8x = 24
x2 – 8x + 144 = 24 + 144

The quadratic equation can be solved by completing square method. The steps to solve the given equation are explained in detail.
What is a quadratic equation?The general form of a quadratic equation is given as ax^2 + bx + c = 0.
Here, a ≠ 0 and b and c are integers.
The degree of a quadratic equation is 2.
The given equation is,
x^2 - 8x -24 = 0
To solve this equation by completing square method, it has to be transformed into the form of (a + b)^2.
The steps for this method are given as follows,
(i) Find the coefficient of x^2. The square root of the this coefficient is the value of a.
(ii) Find the term containing non-square part. In the given case it is -8x.
(iii) Compare the coefficient of this term with 2ab. it gives,
2ab = -8
=> 2 × 1 × b = -8
=> b = -4
(iv) Write the equation in the form of a^2 + 2ab + b^2 leaving the remaining term as it is. For the given equation it can be written as,
x^2 - 8x + 4^2 - 40 = 0
=> x^2 - 8x + 4^2 = 40
(v) Now, write the equation in terms of (a +b)^2 and get the solution. In this case it is written as,
(x - 4)^2 = 40
=> x - 4 = ±√40
=> x = 4 ±√40

What's the largest fraction in each group? a. 5⁄6 and 29⁄36 b. 5⁄12 and 3⁄8 c. 2⁄5 and 19⁄45 d. 5⁄7, 13⁄14, and 19⁄21
Solution :
We have to find the largest fraction in each group.
a). [tex]$\frac{5}{6}$[/tex] and [tex]$\frac{29}{36}$[/tex]
[tex]$\frac{5}{6}$[/tex] → when we divide the number 5 with 6, we get 0.833
[tex]$\frac{29}{36}$[/tex] → when we divide 29 by 36, we get the value 0.805
Therefore, in this group, [tex]$\frac{5}{6}$[/tex] is the largest fraction.
b). [tex]$\frac{5}{12}$[/tex] and [tex]$\frac{3}{8}$[/tex]
[tex]$\frac{5}{12}$[/tex] → when we divide the number 5 with 12, we get 0.416
[tex]$\frac{3}{8}$[/tex] → when we divide 3 by 8, we get the value 0.375
Therefore, in this group, [tex]$\frac{5}{12}$[/tex] is the largest fraction.
c). [tex]$\frac{2}{5}$[/tex] and [tex]$\frac{19}{45}$[/tex]
[tex]$\frac{2}{5}$[/tex] → when we divide the number 2 with 5, we get 0.40
[tex]$\frac{19}{45}$[/tex] → when we divide 19 by 45, we get the value 0.42
Therefore, in this group, [tex]$\frac{19}{45}$[/tex] is the largest fraction.
d). [tex]$\frac{5}{7}$[/tex], [tex]$\frac{13}{14}$[/tex] and [tex]$\frac{19}{21}$[/tex]
[tex]$\frac{5}{7}$[/tex] → when we divide the number 5 with 7, we get 0.714
[tex]$\frac{13}{14}$[/tex] → when we divide 13 by 14, we get the value 0.928
[tex]$\frac{19}{21}$[/tex] → when we divide 19 by 21, we get the value 0.904
Therefore, in this group, [tex]$\frac{13}{14}$[/tex] is the largest fraction.
