lana66690 [7]

Area of ∆ = 1/2 times its base × height
=1/2 × 4 × 5 UNIT²
=10 unit²
Area of semicircle = πr²/2
= (3.14)(4)²/2
=25.12 unit²

Therefore area of figure= 10+25.12 unit² = 35.12 unit²

Mrs. Jones has a local bakery. Last week this expression shows how many peanut butter cupcakes she baked. 5 (2x -4) + 3(3 + 4x)

3241004551 [841]

Answer:

A. $22x-11$

B. $121$ cupcakes

Step-by-step explanation:

Part A:

The simplified form of the expression is

$5(2x-4)+3(3+4x)$

$(10x-20)+(9+12x)$

$(10x+12x)+(9-20)$

$22x-11$

Part B:

Put $x=6$ in the above simplified equation to get the number of cupcakes Mrs. Jones bake last week

$22x-11$

$22(6)-11$

$132-11$

$121$ cupcakes
