Answer:

r = -1

Step-by-step explanation:

This is the answer because:

1) You can take the root of both sides and solve

2) You can also isolate the variable and solve for it

1. r9 + 1 = 0, divide 9 and 0 first. 9 x 0 = 0

2. r + 1 = 0, subtract 0 and 1. 0 - 1 = -1

Hope this helps!

Answer:

${:}\longrightarrow$ $\sf 2x^3+20x^2+2ax^2+20ax$

${:}\longrightarrow$ $\sf 2x^2 (x+10)+2ax (x+10)$

${:}\longrightarrow$ $\sf (x+10)2x^2+2ax$

${:}\longrightarrow$ $\sf (x+10)2x (x+a)$

${:}\longrightarrow$ $\sf 2x (x+a)(x+10)$

Answer:

40.32 sqcm

Step-by-step explanation:

For two similar polygons, ratio of corresponding sides are equal.

Here, ratio of breadth = 4.8/4 = 1.2

So, length of the larger rectangle = 7 * 1.2 = 8.4

So, area of the larger triangle = 4.8 * 8.4 sqcm = 40.32 sqcm

HELP PLEASE!

Archy [21]

Answer:

Option 2 50 ≤ s ≤ 100

Option 5 She could deposit $50

Option 6 She could deposit $75

Step-by-step explanation:

Let

s -----> amount of money Layla deposit into a saving account

we know that

25%=25/100=0.25

50%=50/100=0.50

$s\geq 0.25*200$ -----> $s\geq \$50$

$s\leq 0.50*200$ -----> $s\leq \$100$

The compound inequality is

$\$50 \leq s\leq \$100$

Verify each case

case 1) 25 ≤ s ≤ 50

The statement is false

see the procedure

case 2) 50 ≤ s ≤ 100

The statement is True

see the procedure

case 3) s ≤ 25 or s ≥ 50

The statement is false

Because is s ≤ 100 and s ≥ 50

case 4) s ≤ 50 or s ≥ 100

The statement is false

Because is s ≤ 100 and s ≥ 50

case 5) She could deposit $50

The statement is true

Because the value of s satisfy the compound inequality $\$50 \leq s\leq \$100$

case 6) She could deposit $75

The statement is true

Because the value of s satisfy the compound inequality $\$50 \leq s\leq \$100$

A phone company offers two monthly charge plans. In Plan A, the customer pays a monthly fee of $35 and then an additional 6 cent

Dafna11 [192]

Answer: Plan A will cost less than Plan B for phone use that is less than or equal to 100 minutes

Step-by-step explanation:

Let m be the number of minutes of phone use.

We can convert $35 and $36 to 3500 cents and 3600 cents respectively.

Then, in Plan A, it would cost 3500 + 6m and in Plan B, it would cost 3600 + 5m.

Since we want Plan A to cost less, we can set up an inequality saying:

$3500 + 6m \leq 3600 + 5m$

We can subtract 3500 + 5m from both sides:

$m\leq 100$

Therefore, Plan A will cost less than Plan B for phone use that is less than or equal to 100 minutes.
