Area of rectangle = Length × Width

Length - (3x+2)
Width - (4x+10)

Area of rectangle = (3x+2) × (4x+10)

Area of rectangle = 3x(4x+10) + 2(4x+10)

Area of rectangle = 12x² + 30x + 8x + 20

Area of rectangle = 12x² + 38x + 20

Hence , the area of rectangle is 12x² + 38x + 20 units

Answer:

Step-by-step explanation:

Area of rectangle = length * width

= (3x + 2)(4x + 10)

= 3x *(4x + 10) + 2*(4x + 10)

= 3x *4x + 3x *10 + 2*4x + 2*10

= 12x² + 30x + 8x + 20 {Combine like terms}

= 12x² + 38x + 20

Anestetic [448]

volume= 4×4×5

Therefore he can't pour all the water into the vase because the amount of water is 120cm³ whilst the vase is 80. An amount of water as that can't fill the vase

What is 56 1/4 as a fraction in simplest form?

Luba_88 [7]

We have to simplify $56 \frac{1}{4}$ %

This is a mixed fraction, with 56 as the whole number part and $\frac{1}{4}$ as the fractional part

Such a fraction can be simplified as:

Denominator of simplified fraction = Denominator of mixed fraction

and Numerator of simplified fraction = (Denominator of mixed fraction × Whole number) + (Numerator of simplified fraction)

⇒ Denominator of simplified fraction = 4

and Numerator of simplified fraction = (4 × 56) + (1)

⇒ Numerator of simplified fraction = 225

Hence, the mixed fraction in its simplest form is $\frac{225}{4}$
