Answer:

a = 7

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ = $\sqrt{ab}$

Given

$\sqrt{5}$ ( $\sqrt{18}$ + $\sqrt{32}$ )

Distribute parenthesis by $\sqrt{5}$

= $\sqrt{5(18)}$ + $\sqrt{5(32)}$

= $\sqrt{90}$ + $\sqrt{160}$

= $\sqrt{9(10)}$ + $\sqrt{16(10)}$

= $\sqrt{9}$ × $\sqrt{10}$ + $\sqrt{16}$ × $\sqrt{10}$

= 3 $\sqrt{10}$ + 4 $\sqrt{10}$

= 7 $\sqrt{10}$ ⇒ a = 7

trasher [3.6K]

Answer:

-2

Step-by-step explanation:

absolute value is the distance from zero. it will never be negative. so -6 is 6 away from zero, -8 is 8 away from zero. you can just take off the negative sign and use the number by itself.

Answer:

3,520 yds in 2 hours

Step-by-step explanation:

5,280:1 ; 1 mile an hour is 5,280 feet in an hour

10,560:2 ; 2 miles in 2 hours is 5,280+5,280 (10,560) feet in 2 hours

3 ft = 1 yd ; every 3 feet is a yard, so divide 10,560 by 3

10,560/3 = 3520 yds ; Jorge can walk 3,520 yds in 2 hours

There's nothing more you can say about it besides exactly
what you have already said, until you know the value of 't'.
