Plus means addition and square root means √
3 plus the square root of negative 16: 3 + √-16
Minus means subtraction and square root means √
6 minus the square root of negative 64: 6 - √-64
Its asking you to multiply both quantities.
(3 + √-16) * (6 - √-64)
Best of Luck!
Answer: 
Step-by-step explanation:
You need to use the following formula:
Where "r" is the radius and 
is is the central angle of the arc in radians.
Assuming that that the angle 
is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.
Therefore, you get:
1 + 2 + 3 + 4 + 5 + 67 + 8 = 90
I think this is what you mean right?
Answer:
Volume of figure 1 is 135
Volume of figure 2 is 108
Total Volume:243
Measure of side A is 8cm
Voume=6*7*3=126
Volume=8*3*3=72
Step-by-step explanation:
1.5*9*3=135
2.9*4*3=108
3.108+135=243
Answer:
IJ = 12
Step-by-step explanation:
sum the parts of the ratios, 3 + 3 + 4 = 10 parts
Divide HK by 10 to find the value of one part of the ratio.
40 ÷ 10 = 4 ← value of 1 part of ratio , then
IJ = 3 parts = 3 × 4 = 12
