<h3>Answer = 67</h3>

<h3>Explanation</h3>

#you see the straight line near (2x - 4) ? yeah it totals 180°, so you only need to find the degree of the other side.

#The question already show 90° (L) and 48° so you can get the other side degree by minus 180 with the degree known.

180° - 48° - 90° = 42°

#and so you only need find the rest of the degree. The degree of (2x + 4)

180° - 42° = 138°

#So the (2x + 4)° is 138°

2x + 4 = 138

2x = 138 - 4

2x = 134

x = 134 : 2

x = 67

Joel wanted his mom to buy a super-sized box of his favorite cereal, but his mom didn't think it would fit in her cupboard. The

Lorico [155]

<h3><u>Given</u>:-</h3>

Volume 6,900 cm^3
Length = 23 cm
Width = 10cm

Height of box ??

<h3><u>Solution</u>:-</h3>

$\\\diamond{\underline{\underline{\sf {\;\; Calculating\; Height\; of \; box :-}}}}\\$

$\\ \pink \star \: \: {\underline{\boxed {\bf{ Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h }}} }\; \red\bigstar \\$

Where,

» l denotes Length
» w denotes Width
» h denotes Height

$\\ \sf \implies \: {Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 23 \: \times \: 10 \: \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 230 \: \times \: h} \\$

$\\ \sf \implies \: { \: h \: = \: \frac{6900}{230} \: } \\$

$\\ \sf \implies \: { \: h \: = \: 30 \: {cm }^{3} \: } \\$

$\\ \implies{\underline{\boxed{\frak { Height = 30 \: cm^3 }}}} \; \purple\bigstar \: \\$

$\\\qquad \rule{120pt}{3pt}\\$

Therefore , the Volume of the Box is 30 cm ³.

Jonathan went to the movies with $48 he earned at his after-school job. The ticket cost $8.75. He spent $7.45 for refreshments.

aleksley [76]

Answer:

8.75+7.45=16.2. 16.2 is equal to $16.20 so 48.00-16.20=31.8. Jonathan had $31.80 left.

Alekssandra [29.7K]

Answer:

$4x+8$

Step-by-step explanation:

We have been given an expression $4(x+2)$ . We are asked to find equivalent expression to our given expression.

Using distributive property $a(b+c)=ab+ac$ , we will get:

$4\cdot x+4\cdot2$

$4x+8$

Therefore, the expression $4x+8$ is equivalent to our given expression.
