Describe the error then simplify the expression correctly.<br><br> -5(3+6)=-15+30<br> =15
Rama09 [41]

Answer: 30 should be negative

Step-by-step explanation:

when having an equation like that, you must multiply -5 by 3, which equals to -15, then multiply-5 by 6 which then equals to -30. The correct equation should be -5(3+6)= -15+-30= -45


I think this should be correct, hope this helps!

Given that 23°=√k,determine the value of each of the following in terms of k,without using a calculator
hram777 [196]
Hello,

In order to exist ,k>=0

1) sin (180°+x)=-sin (x) ==>sin(203°)=-√k

2) cos² x +sin² x=1==>cos x=√(1+sin² x)=√(1+k)

3)tan (-x)=-tan (x) =-sin (x)/cos (x) =- √k/√(1+k)=√(k/(1+k))

The formula for the surface area of a right prism is LaTeX: A=2B+PhA = 2 B + P h. Solve for LaTeX: hh. Which equation gives a co
qaws [65]

Answer:

h = \frac{A - 2B}{P}

Step-by-step explanation:

A = 2B + Ph

Required

Solve for h

A = 2B + ph

Subtract 2B from both sides

A - 2B= 2B - 2B+ ph

A - 2B= ph

Reorder

Ph=A - 2B

Divide through by P

h = \frac{A - 2B}{P}
