64; multiply the length (8m) of the terrace and the width (4m) to get the first section with common sense, the other side is the same so 32+32=64,

Hope this helped, good luck!

Hello

14-4x=2y divide 2 to both sides VVVVV7-2x=y you will need this on the next step-----------------------------------------------------y+2x=7y=7-2x(7-2x)+2x=7 -------> 7-2x+2x=7 7=7Have a nice day

Sound fruit seller earns a $0.40 profit for each Apple that it sells and a $0.40 profit for each bananas at its cells which expr

Nikolay [14]

Answer:

$P= 0.4x+ 0.4y$

Step-by-step explanation:

Given data

Profit from apple= $0.4

Profit from banana= $0.4

Let the number of Apples sold be x, and the number of bananas sold be y

and the total profit be P

Hence the expression for the total profit is given as

$P= 0.4x+ 0.4y$

What is the simplified form of 12x/900x²y4z6?

zalisa [80]

Answer:

$360xy^2|xz^3|$

Step-by-step explanation:

Given expression:

$12x \sqrt{900x^2y^4z^6}$

$\textsf{Apply radical rule} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}:$

$\implies 12x \sqrt{900}\sqrt{x^2}\sqrt{y^4}\sqrt{z^6}$

Replace 900 with 30² :

$\implies 12x \sqrt{30^2}\sqrt{x^2}\sqrt{y^4}\sqrt{z^6}$

$\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0:$

$\implies 12x \cdot 30|x|\sqrt{y^4}\sqrt{z^6}$

$\implies 360x|x|\sqrt{y^4}\sqrt{z^6}$

(We need to use the absolute value of √x² since the x term was originally to the power of 2, which means the value of x² is always positive since the exponent is even).

$\textsf{Apply exponent rule} \quad \sqrt{a^m}=a^{\frac{m}{2}}:$

$\implies 360x|x|\cdot y^{\frac{4}{2}}\cdot z^{\frac{6}{2}}$

Simplify:

$\implies 360xy^2|xz^3|$

(We need to use the absolute value of z³ since the z term was original to the power of 6, which means the value of z⁶ is always positive since the exponent is even).
