Answer:
A = 1100cm^2
Step by step Explanation:
given the dimensions of width and length of the picture are x+20 by 2x-10 and the frame is a constant 5 cm wider from the edge of the picture to the frame, than the area of the frame is defined as (x+30)(2x)-(x+20)(2x-10) = 30x+200.
If the width is equal to the length which I assume is true if the width is constant.
than x+30=2x, which means x = 30.
if this is true than 30(30)+200 = 1100cm^2

A quadratic function can be written in the
form h(x) = k(x - a)(x - b), where a and b
are the zeros of the function. Write () hx
in standard form if its zeros are 3 and 4
and k is 5.
Answer:
h(x) = 5x² - 35x + 60
Step-by-step explanation:
Given the zeros are 3 and 4 then the corresponding factors are
(x - 3) and (x - 4), then
h(x) = 5(x - 3)(x - 4) ← expand factors using FOIL
= 5(x² - 7x + 12) ← distribute by 5
= 5x² - 35x + 60 ← in standard form

If you wanted to rotate a shape by 110 by double reflecting it over two intersecting lines, the angle between the two intersecting lines would need to be ___.
If you wanted to rotate a shape by 24 by double reflecting it over two intersecting lines, the angle between the two intersecting lines would need to be ________.
If you wanted to rotate a shape by 200 by double reflecting it over two intersecting lines, the angle between the two intersecting lines would need to be ________.
Answer:
A) 55°
B) 12°
C) 100°
Step-by-step explanation:
A) By double reflecting it over two intersecting lines, the angle between the two intersecting lines would simply be half of the angle at which it was rotated.
Thus, angle between the two intersecting lines = 110/2 = 55°
B) Similarly, for rotating a shape by 24°,
angle between the two intersecting lines = 24/2 = 12°
C) Similarly, for rotating a shape by 200°;
angle between the two intersecting lines = 200/2 = 100°

Find the measure of the angle complementary to the given angle.
mZy = 15°
Answer: 75 degrees
Step-by-step explanation:
The definition of a "complementary angle" is adding up to 90 degrees, and if one of the angles is 15 degrees, that angle measure and the unknown angle measure must add up to 90 degrees. To find the unknown, we subtract 15 from 90, and we get 75. Therefore, the answer is 75 degrees.

What is the slope of the line passing through the points (−3, 4) and (2, −1)? −1 35 −5/3
1
please answer with the reason your right cause i need the 100%
Answer:
The slope would -1
Step-by-step explanation:
When solving these problems we need to know the formula for finding slope between two points which is considered [tex]\frac{y2-y1}{x2-x1}[/tex] in which the y-value on the second coordinate (-1) minus the y-value of the first coordinate (4), these would be put on top of the fraction bar while we do the same for the x-value in which we get the x-value from the second coordinate (2) and do minus the x-value of the first coordinate (-3).
Next let's plug-in our values into the equation [tex]\frac{(-1)-(4)}{(2)-(-3)}[/tex] . With the top part being easy to subtract it would simply be -5 on top. The bottom, however, has a minus on the bottoms with -3 in parentheses, in which case this would then turn into a +3 because distributing the negative to -3 to make it a positive. The bottom of the fraction would then become 2+3 which is 5.
Our final equation would look like [tex]\frac{-5}{5}[/tex] in which case can be simplified to -1.

11. x=16
12. [tex]\sqrt{1081}[/tex] or about 32.88
Step-by-step explanation:
11. Since there's a square you know that the side is 12 on the triangle. You can use the Pythagorean theorem (a^2+b^2=c^2) to find x. In this case, it would be 144+x^2=400. x^2=400-144=256 so x=16.
12. You can find the shortest side of the larger triangle by using the pythagorean theorem. So it would be a^2=169-25 so a=12 then you can use the same theorem and x^2=35^2-12^2=1225-144=1081 so x=[tex]\sqrt{1081}[/tex] which is about 32.88

Answer:
scale factor = 1/2
Step-by-step explanation:
for AC: 4 + 4 = 8
8 is the AC of the red triangle
4 is the AC of the blue triangle
to get from 8 to 4, we divide by 2 or multiply by 1/2 (they mean the same thing)
10 is the CB of the red triangle
5 is the CB of the blue triangle
to get from 10 to 5, we divide by 2 or multiply by 1/2
