Could I get the answer, all work, and explanation for this problem? Thanks

$\bf \sqrt{x+8}+\sqrt{x}=2\implies \sqrt{x+8}=2-\sqrt{x}\impliedby \textit{we raise both at }^2
\\\\\\
(\sqrt{x+8})^2=(2-\sqrt{x})^2\implies x+8=(2-\sqrt{x})(2-\sqrt{x})
\\\\\\
x+8=\stackrel{\textit{and we FOIL here}}{4-4\sqrt{x}+(\sqrt{x})^2}\implies x+8=4-4\sqrt{x}+x
\\\\\\
4=-4\sqrt{x}\implies \cfrac{4}{-4}=\sqrt{x}\implies -1=\sqrt{x}\impliedby \stackrel{again}{\textit{we raise both at }^2}
\\\\\\
(-1)^2=(\sqrt{x})^2\implies 1=x$

galina1969 [7]

Answer:

Heyaa!! Im Pinky!! And Im Here To Inform You That Your Answer Is...

Step-by-step explanation:

!!!! A. 3/8 !!!!

My calculations:

Given

2/3 y = 1/4

Multiply Each Sides by 3!

 2y = 3 × 1/4= 3/4

Then we can Divide both sides by 2!

y= 3/4 ÷ 2 = 3/4 × 1/2 = 3/8!!

Have An Amazingly Good Day!!! (or night!)

A farmer grows crops with an average height of 5 feet. He breeds his tallest plants, which are each 8 feet tall. They produce of

irinina [24]

Answer:

Qa: The heritability for tallness in these crops is 0.08, while Qb: Genes slightly influence the trait for height.

Step-by-step explanation:

Qa: The average height of regular crops grown by the farmer was 5 feet. The amazingly tall breeds have a 3feet increment than the usual crops. This progeny of the farmer's choice breeds has a 0.25 feet increment in height than what is expected in other normal breeds. Therefore, the heritability of the tall trait by these progeny was 0.25/3, which is 0.08333.....Approximately 0.08.

Qb: This low heritability index showed that the trait for tallness is slightly influenced by gene, because if otherwise, the index would have been a far way higher than this. However, we cannot conclude that it is the environment that determines the tall phenotype to be expected in the crops; this renders other options wrong.
