Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
Answer: $380 per week
Step-by-step explanation:
Assuming that Jefferson works the same amount each week, you need to divide the total that he earns by four weeks in order to determine how much he made each week.
$1,520 divided by 4 equals $380 per week.
Answer: Remember the denominator of the fractional exponent will become the root of the radical, and the numerator will become the power. Create the power first and then the root. Create the root first and then the power.

Answer:
60
Step-by-step explanation:
The corresponding angles of the triangles are given, y + 10 and 2y - 40. You need to first find the value of the variable (in this case, y), and to do this, you need to set them equal to one another:
y + 10 = 2y - 40
<u>Subtract y from both sides:</u>
<u />
y + 10 = 2y - 40
-y -y
____________
10 = y - 40
<u>Add 40 to both sides:</u>
<u />
10 = y - 40
+40 +40
________
50 = y
Now that we have the value of y, you need to plug the value into one of the expressions (either one will come out with the same answer):
y + 10
50 + 10 = 60
<em><u>OR</u></em>
<u />
2y - 40
2(50) - 40
100 - 40 = 60
<u />
