372 simplified is: 2*2*3*31. Thus, 372*7= 2*2*3*31*7. I believe that's what the question is asking for, Hope that helps. :)
P = 5 .............................................
this is how=
first you expand the second equation
<span>25 + 4p = -18 + -12 + 6p + 9p
</span>
then you add the like terms in the second equation:
25 + 4p = -30 + 15p
then this is how=
25+30 = 15p -4p
55=11p
p= 5
Answer:
I think degree means the highest exponent, so wouldnt it be 8?
Answer: 75 feet²
Step-by-step explanation:
The scale means that for every one unit in the scale drawing, it is 30 units in the actual room. We will convert the dimensions using proportions.
x = 90
-
x = 120
The area of a rectangle can be found by multiplying the length by the width:
A = L * W
A = 90 * 120
A = 10,800 inches²
To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.
10,800 inches² / 144 = 75 feet²
The area of the room, in square feet, is 75 feet².
Answer:
m∠A = 20°
Step-by-step explanation:
Triangle ABC has the following angle measures:
We know that the addition of the angles of a triangle makes 180°, therefore:
m∠A + m∠B + m∠C = 180°
Replacing with data and solving for x:
2x + 5x + 11x = 180
18x = 180
x = 180/18
x = 10°
Which makes the angles:
m∠A = 2*10 = 20°
m∠B = 5*10 = 50°
m∠C = 11*10 = 110°
