Answer:

C.) 20, 40, 4, 56

Step-by-step explanation:

Equation:

$\frac{1s + 2d + 3t + 4hr}{ab}$

$(1 \times 20) + (2 \times 40) + (3 \times 4) + (4 \times 56) = 336$

$336 \div 400 = .84$

.84 as a percentage is 84.5%

84.5% is greater than .500 or 50%

PLS ANSWER QUICK! Thanks!

Answer:

The correct answer would be $a=\sqrt{c^2-b^2}$

Step-by-step explanation:

given $a^2+b^2=c^2$ we want to solve for a

How?

We can do this by using basic algebra ( isolating the variable (a ))

Step 1 subtract $b^2$ from each side

$a^2+b^2-b^2=a^2\\c^2-b^2=c^2-b^2$

now we have $a^2=c^2-b^2$

step 2 take the square root of each side

$\sqrt{a^2} =a\\\sqrt{c^2-b^2} =\sqrt{c^2-b^2}$

we're left with $a=\sqrt{c^2-b^2}$

Hence your answer is A

Solve v^2+2v=0 by factoring

Yuki888 [10]

$\large \mathfrak{Solution : }$

let's factorise :

${v}^{2} + 2v = 0$

$v(v + 2) = 0$

now, there are two cases :

case 1 :

$v = 0$

case 2 :

$v + 2 = 0$

$v = - 2$
