IM IN A TEST NOW WILL AWARD BRAINLIEST!!!!!

The product has decreased by 80 %

Solution:

The product of the original numbers: xy

One number is decreased by 75 %

Let x be the number decreased by 75 %

new number = x - 75 % of x

$new\ number = x - 75 \% \times x\\\\new\ number = x(1-75 \%)\\\\new\ number = x(1-\frac{75}{100}) = x(1-0.75) = 0.25x$

Another number is decreased by 20 %

Let y be the number decreased by 20 %

new number = y - 20 % of y

$new\ number = y - 20 \% y\\\\new\ number = y(1-20 \%)\\\\new\ number = y(1-\frac{20}{100}) = y(1-0.2) = 0.8y$

Now the product is given as:

$product = 0.25x \times 0.8y = 0.2xy$

Now we have to find the percent decreased

Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage

$percent\ decrease = \frac{0.2xy - xy}{xy} \times 100\\\\percent\ decrease = \frac{-0.8xy}{xy} \times 100 = -0.8 \times 100 = -80$

Here negative sign denotes decrease

Thus the product has decreased by 80 %

What is the quotient: (2x2 + 10x + 12) ÷ (x + 3) ?

NARA [144]

The answer is C. Factor the equation: 2x^2 + 10x + 12 which gives you............. 2(x + 2) (x + 3), and then cancel out (x + 3) because dividing (x + 3) by itself gives you one and the remaining term is 2(x +2) which is the same as 2x +4.
