Answer:
29t + 24
Step-by-step explanation:
5(5t + 6) + 2(2t - 3)
Open Parentheses first.
5* 5t = 25t
5 * 6 = 30
25t + 30 + 2(2t - 3)
Open others
2 * 2t = 4t
2 * 3 = 6
25t + 30 + 4t - 6
Match like terms
29t + 24
Answer:
150ft²
Step-by-step explanation:
surface area = (2×½×8×3)+(8+5+5)×7
= 24+126
= 159 ft²
Answer:
The formula for the volume of a cone is 1/3 Bh. This means 1/3 the Area of the base times the height. You can calculate the area by multiply length and width. Area is two-dimensional. Multiplying height by it adds another dimension. When writing area, we say units squared. When writing volume, we say units cubed, because it is three dimensional.
Step-by-step explanation:
Answer:
a mathematical sentence thar has an equal sign
The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.
1. 4x + 3 = 3x +12
Subtract 3x from each side:
x +3 = 12
Subtract 3 from both sides:
x = 9
2. -2 + x = 2x -7
Subtract 2x from both sides:
-2 - x = -7
Add 2 to each side:
-x = -5
Multiply both sides by -1:
x = 5
