Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144
cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
V = 7x6x5 = 210
Your answer is 4
You have to use the distribute property and distribute the - to the -7 and the 3
The -7 will become and the 3 will become -3
Then you add those together and when you add a negative to a positive you basically subtract
So 7+-3 is 4
A is your answer
Answer: Rotation
Step-by-step explanation: can't be translation its tilted cant be reflection because of the tilt also cant be dilation because its the same size {hope this help's :{
Answer:
11.25
Step-by-step explanation:
Since AB and CD are parallel, ∠D is congruent to ∠A and ∠C is congruent to ∠B. Therefore the two triangles are similar by the AA postulate. Now, the corresponding sides are in proportion
Since AE ↔ DE and AB ↔ CD
So, AE/CD = AB/CD
AE/5 = 9/4
AE = 9(5)/4
= 45/4 = 11.25
