# A rectangular prism has side lengths of 4 inches, 6 inches, and 7 inches. If all side lengths are multiplied by 5, what happens to the surface area.A) It remains the same. B) It is multiplied by 5. C) It is multiplied by 25. D) It is multiplied by 125.

C

Step-by-step explanation:

The surface are of the prism will be the area of a each side added together. The work would look like this:

SA = 2[(l×h)+(l×b)+(b×h)]

SA = 2(lh+lb+bh)

But if you multiply each dimension by 5, the area becomes

SA = 2[(5l×5h)+(5l×5b)+(5b×5h)]

SA = 2(5²lh+5²lb+5²bh)

SA = 5²×2(lh+lb+bh)

SA = 5²area

Since 5² = 25, then the the surface area is multiplied in size by 25.

Suppose ΔABC= ΔDEF, AB =6 feet, m∠B=65 degrees, and m∠f=33 degrees. True or false ED=6ft

true because ABC and DEF are equal so if AB equals 6 ED must equal 6 since it’s the same just the order is reversed

Estimate the value of this expression by rounding each number to the nearest whole unit. (1.74)(9.95)(3.46) A. 80 B. 54 C. 60 D. 72

The answer is C. 60 because if you multiply 1.74*9.95*3.46 you will get 59.90298 and if you round to the nearest whole then it's 60

132,554 round to nearest tenth

Answer:if you ment "round to the nearest tens" and not tenths. your answer would be 132,550. and if you ment to put a decimal like 132.550 your answer would be 132.6

places values:
one hundred thousand, ten thousands, thousands, hundreds, tens, ones, tenths, hundredths, thousands
132,554 is already rounded to the nearest tenth
