Use the diagram below to answer questions 1-6. All rooms are rectangular. 1. What is the value of side A? Explain your thinking.

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

1) A = x

Flower garden is in rectangular shape. In rectangle, opposite sides are equal.

2) The entire garden is in rectangular shape. In rectangle, opposite sides are equal.

B + x+ 4 = 10x + 6

Take x and 4 to other side to find the value of B. When taking to other side of equal to sign, the sign of x and 4 will change

B = 10x + 6 - x - 4

B = 10x - x + 6 - 4 {Combine like terms}

B = 9x + 2

3) C + x -2 = 5x -3

C = 5x - 3 - x +2

C = 5x -x - 3 + 2

C = 4x - 1

4) Area of Vegetable garden = length * width

= (5x - 3) * (9x + 2)

Use FOIL method

= 5x *9x + 5x*2 + (-3)*9x + (-3)*2

= 45x² + 10x - 27x - 6

= 45x² - 17x - 6

Suppose j varies jointly with g and v, and j=2 when g=4 and v=3. Find j when g=8 and v=9.

vladimir2022 [97]

Answer:

$j=12$

Step-by-step explanation:

we know that

In a join variation, If j varies jointly with respect to g and v, the equation will be of the form $j = kgv$

where k is a constant

step 1

Find the value of k

we have

j=2,g=4,v=3

substitute and solve for k

$2 = k(4)(3)$

$2 = 12k$

$k=\frac{1}{6}$

The equation is equal to

$j=\frac{1}{6}gv$

step 2

Find the value of j when g=8,v=9

substitute the values in the equation and solve for j

$j=\frac{1}{6}(8)(9)$

$j=12$

X=6 is a solution to the inequality x−5≤ 10 True or False?

vekshin1

Answer:

$\boxed{\sf{FALSE}}$

$\boxed{\sf{x\leq 15}}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 5 from both sides.

$\sf{x-5+5\leq10+5}$

Solve.

Add the numbers from left to right.

$\sf{10+5=15}$

$\Longrightarrow: \boxed{\sf{x\leq 15}}$

Therefore, the solution is x≤15, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.
