The Martins bought a house this year for $300,000. If the value of the house rises 4% each year, what will be the approximate va

tigry1 [53]

I believe it’s 30,180,000

First do 4% -> 0.04x15=0.6
0.6+100=100.6x300,000

But then again I’m not too sure so double check

Four times the square of a certain number increased by 6 times the number equals 108.find the number

slamgirl [31]

To effectively determine the correct answer, it would be helpful to write this into an algebraic expression. We let x as the number. We do as follows:

Four times the square of a certain number increased by 6 times the number equals 108.

4x^2 + 6x = 108

The numbers can be either of the following since the equation generated was a quadratic equation which has two roots.
x = 4.5
x = -6

Which property was used to simplify the expression? (3z)^2 = 3^2z^2 = 9z^2

svet-max [94.6K]

One of the product rules for exponents was used.
$(ab)^{c}=a^{c}b^{c}$

Or, you can consider that the definition of an exponent and the associative and commutative properties of multiplication were used.
$(3z)^{2}\\=(3z)(3z)\\=3\cdot 3\cdot z\cdot z\\=3^{2}z^{2}\\=9z^{2}$

A suncatcher has 6 sections. Each section is in the shape of a parallelogram witha base of 12 cm and a height of 8 cm. What is t

jonny [76]

Answer:

576 cm²

Step-by-step explanation:

Given:

Number of sections in a suncatcher (n) = 6

Each section is in the shape of a parallelogram.

Base of parallelogram = 12 cm

Height of parallelogram = 8 cm

Now, area of a parallelogram is given as:

Area of parallelogram = Base × Height

Area of 1 parallelogram = 12 cm × 8 cm = 96 cm²

Now, there are 6 parallelogram shaped sections.

So, area of the sections = area of 1 section × total number of sections

∴ Area of 6 sections = 96 cm² × 6 = 576 cm²

Therefore, the total area of the sections of a suncatcher is 576 cm².
