You would just replace x with 2 in the part equation and solve for it. So 3(2) - 7. This is equal to -1

A garden contains two square peanut beds. Find the length of each bed if the sum of the areas is 914ft squared and the differenc

garik1379 [7]

Answer:

The answer to your question is:

m = length of the smaller bed = 17 ft

l = length of the larger bed = 25 ft

Step-by-step explanation:

Data

A1 + A2 = 914

A1 - A2 = 336

A1 = l²

A2 = m²

Process

l² + m² = 914

l² - m² = 336

l² = 336 + m²

(336 + m²) + m² = 914

336 + 2m² = 914

2m² = 914 - 336

2m² = 578

m² = 578 / 2

m² = 289

m = 17 ft

l² = 336 + 289

l² = 625

l = 25 ft

Simplify the expression:

n200080 [17]

Answer:

1. -b^2+13b

2. 1.9y^2-1.4y+4

Step-by-step explanation:

1. -0.8b^2+7.4b+(5.6b-0.2b^2)

Simplify: -0.8b^2+7.4b+5.6b-0.2b^2

Add like terms: (-0.8b^2-0.2b^2)= -1b^2/-b^2 (7.4b+5.6b)= 13b

Answer: -b^2+13b

2. (7.3y-y^2+4)+0.5y^2-(8.7y-2.4y^2)

Simplify: 7.3y-y^2+4+0.5y^2-8.7y+2.4y^2

Add like terms: (2.4y^2-y^2)= 1.9y^2 (7.3y-8.7y)= -1.4y (don't forget about the 4)

Answer: 1.9y^2-1.4y+4

Answer:

36 cm

Step-by-step explanation:

Because the plant is growing the same amount each week you would take 12(3) and get 36 cm at the end of the 12 weeks.

Emily measured the height of a dresser as 4.27 feet, but the actual height was 4 feet. What is the percentage of error in Emily’

Assoli18 [71]

We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:

4.27 - 4 = 0.27

Now we can set up a proportion to find the percentage.

$\frac{0.27}{4} \frac{x}{100}$

Solve for x

0.27 x 100 = 27
27/4 = 6.75

The answer is 6.75% :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
