A rectangle sticker had a perimeter of 32 centimeters and a area of 48 square centimeters. what are the dimensions of the sticke

vovangra [49]

Answer:

4 cm ×12 cm

Step-by-step explanation:

To find the dimensions of the sticker, start by forming 2 equations for its area and perimeter.

Perimeter of rectangle= 2(length +breadth)

Let the length and breadth of the rectangle be L and B cm respectively.

2(L +B)= 32

Divide both sides by 2:

L +B= 16 -----(1)

Area of rectangle= length ×breadth

LB= 48 -----(2)

From (1): L= 16 -B -----(3)

Substitute (3) into (2):

(16 -B)(B)= 48

Expand:

16B -B²= 48

B² -16B +48= 0

(B -4)(B -12)= 0

B -4= 0 or B -12= 0

B= 4 or B= 12

Substitute into (3):

L= 16 -4 or L= 16 -12

L= 12 or L= 4

Thus, the dimensions of the sticker is 4 cm ×12 cm.

What is the answer (7t2+4t+1)–4t2

Solnce55 [7]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{3 {t}^{2} + 4t + 1}}}}}$

Step-by-step explanation:

$\sf{ (7 {t}^{2} + 4t + 1) - 4 {t}^{2} }$

Remove the unnecessary parentheses

$\longrightarrow{ \sf{7 {t}^{2} + 4t + 1 - 4 {t}^{2} }}$

Collect like terms

$\longrightarrow{ \sf{7 {t}^{2} - 4 {t}^{2} + 4t + 1}}$

$\longrightarrow{ \sf{3 {t}^{2} + 4t + 1}}$

Hope I helped!

Best regards! :D
