8 and 0 add up to equal eight. 8+0=8. When multiplied, the answer is zero. 8*0=0. In fact, any number times zero will always be zero :)

I really need help guys can some one plz help me it's for 10 points

Answer:

\sqrt{8}----- 2units,2units

\sqrt{7} ------\sqrt{5}units,\sqrt{2}units

\sqrt{5}-------1unit,2units

3------2units, \sqrt{5}units

Step-by-step explanation:

Use pythagorean's theorem to solve each pair individually.

The instructions say that you have the two sides (a and b) and you have to match it with their hypothenuse.

Formula: c^2=a^2+b^2

1. a=\sqrt{5}, b=\sqrt{2}

Plug this into the formula.

c=\sqrt{(\sqrt{5} )^2+(\sqrt{2})^2 }

The square here eliminates the roots.

c=\sqrt{5+2}\\ c=\sqrt{7}

2. a=\sqrt{3}, b=4

c=\sqrt{(\sqrt{3} )^2+(4)^2}\\ c=\sqrt{3+16}\\ c=\sqrt{19}

3. a=2, b=\sqrt{5}

c=\sqrt{(2)^2+(\sqrt{5})^2 }\\ c=\sqrt{4+5}\\ c=\sqrt{9}\\ c=3

4. a=2, b=2

c=\sqrt{(2)^2+(2)^2}\\ c=\sqrt{4+4}\\ c=\sqrt{8}

5. a=1, b=2

c=\sqrt{(1)^2+(2)^2}\\ c=\sqrt{1+4}\\ c=\sqrt{5}

What value of t satisfies the equation t/8-3/4=9/16
kogti [31]
\frac{t}{8} - \frac{3}{4} = \frac{9}{16}   Multiply both sides by 8 to get t out of the fraction
t - \frac{3 x 8}{4} = \frac{9 x 8}{16}   Simplify the numerators
t - \frac{24}{4} = \frac{72}{16}   Divide the fractions
t - 6 = 4 \frac{1}{2}   Add 6 to both sides
t = 10 \frac{1}{2}
