Answer:
5.7 meters
Step-by-step explanation:
Image a rectangle being cut diagonally in half, that would lead to two triangles. We can use the pythagorean theorem to find the missing side.
7 is the hypotenuse and 4 is the side length
4^2+x^2=7^2
16+x^2=49
sqrx=sqr(49-16)
x=sqr33
x=5.74
Rounded to the nearest tenth is 5.7
Answer:
x=-48
Step-by-step explanation:
Add 4 to both sides and then multiply both sides by 3.
Answer:
3.5
Step-by-step explanation:
2x1/4=0.5
0.5x7=3.5
=3.5
Answer:r=7/7744
move all terms to the left:
(7/22)(44)-(2r)=0
add all the numbers together, and all the variables
-2r+(+7/22)44=0
multiply parentheses
-2r+7/22*44=0
multiply all the terms by the denominator
-2r*22*44+7=0
multiply elements
-1936r*4+7=0
multiply elements
-7744r+7=0
move all terms containing r to the left, all other terms to the right
-7744r=-7
r=-7/-7744
Answer:
a and d are both true. The rest are not.
Step-by-step explanation:
1 and 6 are like terms. They are both integers. They can be combined. This statement is true.
7 is a numerical coefficent. This statement is true.
===========================================
The others are all false for one reason or another
b is false. The factor is made up of 2 terms not 3. 7a is one term.
c is false. "a" is a variable. So the whole term can be anything.
e is false. 7a + 2 is a factor
f is false. There are two true statements.
