The rectangle below has an area of 144x4 square meters and a width of 12x meters. What is the length of the rectangle?

Alex777 [14]

<h3>The length of rectangle is 12x³ metres .</h3>

As we know that

♦ Area of rectangle = Length × breadth

Substituting known values ,

⇒ 144x⁴ = 12x ( Length )

⇒ 144x⁴ / 12x = Length

⇒ 12x³ = Length

⇒ Length = 12 x³

Write x4 * x2 without exponents.

AveGali [126]

Hey there!

It’s very much impossible to make this equation without it being an exponent because the result has an exponent in it itself

x⁴ × x²

= (x × x × x × x) + (x × x)

≈ x⁴ ⁺ ²

≈ x⁶

Therefore, the answer should be: x⁶

Good luck on your assignment & enjoy your day!

Debra's rectangular vegetable garden measures 93 yards by 12 yards.

77julia77 [94]

Answer:

126 cups of fertilizer

Step-by-step explanation:

<u><em>The complete question is</em></u>

Debra's rectangular garden measures 9 1/3 by 12 yards .a bottle of fertilizer cost $14.79 .if Debra needs to mix 1/8 cup of fertilizer with water for each square foot of her garden how many cups of fertilizer does she need?

step 1

Find the area of the rectangular garden

The area of rectangle is equal to

$A=LW$

we have

$L=9\frac{1}{3}\ yd=9+\frac{1}{3}=\frac{9*3+1}{3}=\frac{28}{3}\ yd$

$W=12\ yd$

substitute

$A=(\frac{28}{3})12=112\ yd^2$

step 2

Convert square yards to square feet

Remember that

$1\ yd=3\ ft$

$1\ yd^2=9\ ft^2$

$112\ yd^2=112)9)=1,008\ ft^2$

step 3

Find how many cups of fertilizer does she need

using proportion

$\frac{(1/8)}{1}\ \frac{cups}{ft^2}=\frac{x}{1,008}\ \frac{cups}{ft^2}\\\\x=1,008/8\\\\x=126\ cups$
