A. 36 cm2
B. 60 cm2
C. 66 cm2
D. 72 cm2
What is the surface area of the geometric figure that - 1

Answers

Answer 1
Answer:

Answer:

Option D.

Step-by-step explanation:

The area of a rectangle is

Area=length * width

In the given net we have 6 rectangles with three pairs of congruent rectangles.

Rectangle 1 and 5 are congruent with length 3 cm and width 2 cm.

A_1=A_5=3 * 2=6

Rectangle 2 and 4 are congruent with length 6 cm and width 3 cm.

A_2=A_4=6 * 3=18

Length of width of rectangle 3 are 6 cm and 2 cm respectively.

A_3=A_6=6 * 2=12

The total area of the figure is

A=A_1+A_2+A_3+A_4+A_5+A_6

A=6+18+12+18+6+12

A=72

The area of figure is 72 square cm. Therefore, the correct option is D.
Answer 2
Answer: The surface area is 72cm squared

(4x^2-25)/(2x-5)=14
we hates fractions so m ultiply both sides by (2x-5)
4x^2-25=14(2x-5)
4x^2-25=28x-70
add 70 to both sides
4x^2+45=28x
subtract 28x  fromoth sides
4x^2-28x+45=0
use quadratic formula which is
if you have
ax^2+bx+c=0 then
x=\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}
a=4
b=-28
c=45
subsitute
x=\frac{-(-28)+/- \sqrt{(-28)^(2)-4(4)(45)} }{2(4)}
x=(28+/- √(784-720) )/(8)
x=(28+/- 8)/(8)
x=(5)/(2) or (9)/(2)
if we were to put 5/2 for x, the deonomentor would be equal to zero, so it cannot be used


answer is
x=9/2

What is multiplication

Answers

It's pretty much combining a lot of addition into a smaller equation. For example, if you don't want to write it all out like 7+7+7+7+7+7+7=49, then you can condense it to 7*7=49. Another example is 6+6=12 is the same as writing 6*2=12.

The measure of an angle is 3/4 of 60 degrees. What is the measure of the complementary angle?

Answers

First we can convert the fraction into a decimal which would be 0.75. Then we continue to multiply  0.75 by 60 which would then give us the answer. 0.75*60=45 degrees We can prove this by dividing 90/2 which equals 45 because 2 complementary angles add up to 90 degrees. 45 degrees is the final answer. Hope this helps!

3/4 x 60/1 = 40 I don't know I'm sorry.
