Question is in the picture

irakobra [83]

Answer:

49.4 (rounded to the nearest tenth)

Step-by-step explanation:

You need to use the Pythagorean theorem -> $a^{2} + b^{2} = c^{2}$ -> $c^{2}$ is the hypotenuse

$a^{2} + b^{2} = c^{2}$

$(7x + 7)^{2}$ + $5x$ = $c^{2}$

(7x $7)^{2}$ + (5x7) = $c^{2}$

$49^{2}$ + 35 = $c^{2}$

2436 = $c^{2}$

$\sqrt{2436}$ = c

c = 49.355850717

c = 49.4 (round to the nearest tenth)

hope this helps, sorry if it is not right

Airida [17]

Answer:

$Balance = \$2.23$

Step-by-step explanation:

Given

$Allowance = \$30$

$Video\ Game = \$17.99$

$Chocolate\ Bar = \$0.79$

$Remote\ Car = \$8.99$

Required [Missing from the question]

What is his balance after purchasing the items

First, calculate total cost of items

$Total =Video\ Game + Chocolate\ Bar + Remote\ Car$

$Total = \$17.99 + \$0.79 + \$8.99$

$Total = \$27.77$

The balance is then calculated as:

$Balance = Allowance - Total$

$Balance = \$30 - \$27.77$

$Balance = \$2.23$
