Consider the isosceles triangle. left side (2z+8)units, bottom of triangle (4z-10)units, right side of triangle (2z+8) units Part A Which expression represents the perimeter of the triangle? a.(4z+16) units b.(6z−2)units c.(8z−16) units d.(8z+6) units

Answer:

d. (8z + 6) units

Step-by-step explanation:

The formula for the Perimeter of a Triangle is :Side A + Side B + Side C

Hence,

(2z + 8)units + (4z - 10) units + (2z + 8)units

= (2z + 8 + 4z - 10 + 2z + 8)units

Collect like terms

= 2z + 4z + 2z + 8 - 10 + 8

= 8z + 6 units

The expression that represents the perimeter of the triangle is (8z +6) units

Differentiate f(x)= square root of x times sin x

zysi [14]

Hello,

$y= \sqrt{ x*sin(x) } \\

y'= \dfrac{sin(x)+x*cos(x)}{2 \sqrt{x*sin(x)} }$

18 is 75 percent of what number

dimulka [17.4K]

18 is 75% of x.

$75\%= \frac{75}{100}=\frac{3 \times 25}{4 \times 25}=\frac{3}{4} \\ \\
\frac{3}{4}x=18 \\
x=18 \times \frac{4}{3} \\
x=6 \times 4\\
x=24
$

18 is 75% of 24.
