Solve for x in the parallelogram. The solution is x= units.

natka813 [3]

$\textit{area of a parallelogram}\\\\ A=bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ b=13\\ A=104\\ h=x \end{cases}\implies 104=(13)(x)\implies \cfrac{104}{13}=x\implies 8=x$

Ok i have a few questions please give examples and descriptions as well

Arte-miy333 [17]

Answer:

1) Multiplying powers with the same base would be product rule. It where you just add the exponents. Dividing powers with the same base would be the quotient rule. Its where you subtract the exponents.

2)Where you multiply the two exponents together

3)The negative law is where for example, if it were in the numerator, then it would be placed at the denominator with a positive exponent whereas if it were in the denominator it would be on the numerator with the positive exponent. The zero law just states the anything to the power to zero is one.

Step-by-step explanation:

1) 3^3 x 3^4 = 3 ^3+4 = 3^7

3^9 ÷3² = 3^9-2 = 3^7

2) (3^2)^2 = 3^2×2 =3^4

3) 1/3^-5 = 3^5 \

The table shows the proportional relationship between a hedgehog's weight loss and the number of days of hibernation. How much

pantera1 [17]

Using the principle of proportional relationship, the amount of weight lost by hedgedog in 120 days is 3.6 oz

Proportional relationships are defined thus :

y = kx
k = constant of proportionality

Taking a piar of points :

-0.24 = 8k

Divide both sides by 8

(-0.24/8) = k

k = - 0.03

Hence, hedgedog loses weight at a rate of - 0.03 oz per day.

The amount of weight lost in 120 days :

The proportional relationship = y = - 0.03x

Substitute x into the equation

y = -0.03(120)

y = - 3.6 oz

Therefore, the amount of weight lost in 120 days is 3.6 oz.
