Tonya has a rectangular rug as shown. The rug is 4 feet longer than it is wide. (Part A) Create an expression that can be used t

Lapatulllka [165]

Answer: $x(x+4)$

Step-by-step explanation:

Given

The rug is 4 feet longer than its width

Suppose the length of the width is x

Length is given by x+4

So, the product of length and width is equal to the area of the rug

$\Rightarrow x\left(x+4\right)=A\quad\quad [\text{A=Area of rug}]$

Find The area of The rectangle below \ 7 FT 6/10 FT

hodyreva [135]

Lets first simplify the dimensions of the rectangle
length = 7
breadth = $\frac{6}{10}$ = $\frac{3}{5}$ = 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6

Area of rectangle = 4.2

Hope it helped you.. :D

Plz help me and explain how you got the answer

Reptile [31]

So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.

Pls help with all the questions

QveST [7]

Answer:

Step-by-step explanation:

Since, CD is an altitude, ∠CDB will be a right angle.

m∠CDB = m∠CDA = 90°

By applying triangle sum theorem in ΔABC,

m∠CAB + m∠CBA + m∠ACB = 180°

20° + m∠CBA + 90° = 180°

m∠CBA = 180° - 110°

= 70°

Therefore, m∠CBD = 70°

By applying triangle sum theorem in ΔBCD,

m∠BCD + m∠CDB + m∠DBC = 180°

m∠BCD + 90° + 70° = 180°

m∠BCD + 160° = 180°

m∠BCD = 20°

m∠CAD = m∠A = 20°

m∠ACD = 90° - m∠BCD

= 90° - 20°

m∠ACD = 70°
