Answer:
480 cm²
Step-by-step explanation:
New side lengths:
80% of 30 cm = 0.8% × 30 cm = 24 cm
80% of 25 cm = 0.8 × 25 cm = 20 cm
area = length × width
area = 24 cm × 20 cm
area = 480 cm²
Answer:
For grid, Please see attachment area of rectangle.
Explanation:
We are given the area of rectangle is 1,125 square unit whose one side is 25 units.
As we know the formula of area of rectangle 
Let 25 units is width of rectangle
Area = 1,125
units
Dimension of rectangle 45 x 25.
Now we draw the grid graph of rectangle.
First we take a grid paper with 1 square unit area of each box. Now we draw line with 45 unit horizontal(Length) and 25 unit vertical (Width).
We make a closed figure with four line opposite side equal and parallel.
Inside box, total number of box must be 1,125 because area of 1 small box 1 square unit.
Total area of all box = 1,125 x 1 = 1,125 square units.
Answer:
The correct answer is -30
Step-by-step explanation:
4(x+32)=8 basically you multiply 4 times the numbers that are in the parentesis which that will equals to 4x+128 because 4x1= 4x and 4x32 = 128. then you subtract 128 from 8 which equals to -120. you divide -120 by 4 which equals to -30.
Answer:
x = 13
Step-by-step explanation:
one of the rules of logarithm (for all bases, by the way, not just e for ln) is

so, we have
ln(3²) = ln(x-4)
=>
3² = x - 4
9 = x - 4
x = 13
Answer:
ok the answer should be A.
Step-by-step explanation:
you transform the coordinates from (x,y) to (-y,x)
this means to flip the coordinates like bring y up front and change its sign and take x to the initial y position.
for example if (-1,9) when you do the transformation you get (-9,-1). you take initial -1 to the right and bring 9 to left and change its sign.
when you are done you can see that the x axis coordinates are the same but the y axis coordinates are the direct opposite. this means that after the transformation the triangle would look like the mirror image of the original triangle.
