Answer:
a. (3x² - 2x - 5) units²
b. (x² - x) units²
c. (2x² - x - 5) units²
Step-by-step explanation:
a. Area of the frame = L*W
L = (x + 1) units
W = (3x - 5) units
Area of the frame = (x + 1)(3x - 5)
Apply distributive property
x(3x - 5) +1(3x - 5)
3x² - 5x + 3x - 5
Area of the frame = (3x² - 2x - 5) units²
b. Area of the picture = L*W
L = x units
W = (x - 1) units
Area of the picture = x(x - 1)
Apply distributive property
= x² - x
Area of picture = (x² - x) units²
c. Area of the frame that surrounds the picture = area of frame - area of picture
= (3x² - 2x - 5) - (x² - x)
= 3x² - 2x - 5 - x² + x (distributive property)
Add like terms
= 3x² - x² - 2x + x - 5
= 2x² - x - 5
Area of the frame that surrounds the picture = (2x² - x - 5) units²
Answer:#1 C.30 #2 40
Step-by-step explanation:
3x+15=7x-5
3x+15+5=7x-5+5
3x+20=7x
3x-3x+20=7x-3x
20=4x
20/4=4/4x
5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30
So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180
4x-48+3x+4=180
7x-44=180
7x=224
x=32
2(32)-24
64-24=40
I only know the first part (~_~;) it's a decaying function
Step-by-step explanation:
Sorry I couldn't give you more info
We need to find which statement is not true:
Let us check each statement:
-They are opposite numbers.
Opposite numbers have the same distance away from zero. Hence, 7 and -7 are opposite numbers.
-They form a zero pair:
7-7 =0, the statement is true.
- They have the same absolute value
The absolute value is the not negative value no matter the sign.
Hence, l7l= 7 and l-7l= 7.
-They have a sum of -14.
Then:
7+(-7) = 0
Therefore, the last statement "They have a sum of -14" is not true.
