Answer:
392
Step-by-step explanation:
m = 8 and n = 14
Substituting the values of m and n in the question, we get :
7m + 3mn
=( 7 x 8) +(3 x 8 x 14)
= 56 + 336
= 392
Answer:
you add your number and then you subtract it so all the other steps are are going to be the exact same
Answer:
The dimensions of the garden are 22.5ft by 27.5ft
Step-by-step explanation:
Here, we want to calculate the dimensions of the garden.
let the length be x ft
we are told that the he wants the length to be 5 feet more than the width;
That means the width will be (x-5) ft
Mathematically;
Since the shape is rectangular, the perimeter will be 2( l + w)
Thus; 2(x + x-5) = 100
2(2x-5) = 100
divide both sides by 2
2x-5 = 50
2x = 50 + 5
2x = 55
x = 55/2
x = 27.5 ft
The width is thus; 27.5ft - 5ft = 22.5ft
the dimensions of the garden are 27.5 ft by 22.5 ft
<em>To solve for a variable, you just need to isolate the variable to one side.</em>
<h3>7.</h3>
For this, just divide both sides by r and <u>your answer will be 
</u>
<h3>8.</h3>
For this, divide both sides by nR and <u>your answer will be 
</u>
<h3>9.</h3>
Firstly, multiply both sides by T: 
Next, subtract FV on both sides of the equation: 
Lastly, multiply both sides by -1, and <u>your answer will be 
</u>
<h3>10.</h3>
Firstly, multiply both sides by 1000: 
Lastly, divide both sides by tc and <u>your answer will be 
</u>
The 2 numbers cannot be positive but the 2 numbers can be both positive and negative like: 2+(-3)= -1. Both numbers can also be negative like: (-3)-(-2)=-1.
