From the given dimensions of the pentagonal prism, the scale factor for both figures is 9:36 which is also equal to 1:4. For the ratio of their volume, we just have to cube the ratio of the measurement of the sides which will give us an answer of 1:64. Therefore, the volume of the larger prism is 64 times as that of the smaller prism.
Answer:
Thus, the value of expression is .
Step-by-step explanation:
Given : 3 + (2 + 8)power 2 ÷ 4 × 1 over 2 to the power of 4
Mathematically written as
We apply BODMAS,
Where ,
B stands for brackets
O stands for order
D stands for division
M stands for multiplication
A stand for addition
S stands for subtraction.
Consider the given expression,
Using BODMAS rule, solving for brackets first,
Thus, the value of expression is
Answer: x=4 or x=−7
Step-by-step explanation:
Because.....
Step 1: Subtract 28 from both sides.
x^2+3x−28= 28 − 28
x^2+3x−28 = 0
Step 2: Factor left side of equation.
(x−4)(x+7)=0
Step 3: Set factors equal to 0.
x−4=0 or x+7=0
x=4 or x=−7
