20 percent of 100 is 20 so the dress is 80 on sale so you need 20 which is 25% of 80
20 plus 80 equal 100 the starting price
25%

enyata [817]

Answer:

$(2x^2+16x+32)\ \text{sq. inches}$

Step-by-step explanation:

b = h = Base = Height of triangle = $(x+4)\ \text{inches}$

Area of one triangle

$A=\dfrac{1}{2}bh=\dfrac{1}{2}(x+4)(x+4)$

There are 4 colored triangles so total area of the triangles is

$4A=4\times \dfrac{1}{2}(x+4)(x+4)\\\Rightarrow 4A=2(x+4)^2\\\Rightarrow 4A=2(x^2+8x+16)\\\Rightarrow 4A=2x^2+16x+32$

The area of the colored triangles is $(2x^2+16x+32)\ \text{sq. inches}$

Jackie made $28 babysitting last week. her brother joe made only 86% as much as she did. how much did joe make?

strojnjashka [21]

Her brother joe made $52.08. First you need to make the percent into a decimal, like this 86% => .86. Then multiply .86 to $28. After that add what you got to $28.
