Answer:
Yes
Step-by-step explanation:
Since the longest side is 6.5 cm, so let it be hypotenuse c.
Verifying by right angle formula
c^2=a^2+b^2
(6.5)^2=(3.9)^2+(5.2)^2
42.25=15.21+27.04
42.25=42.25
Hence the given triangle is a right angles triangle
Answer:
2r(d-2)
Step-by-step explanation:
1. 2 and r are both factors of the monomials 2dr and -4
2. Put it as 2r and divide each monomial and put it into parentheses.
3. 2dr/2r is "d" while -4r/2r is -2 since the r cancels out
3. After your done dividing each term b your GCF multiply your GCF to whatever is in the parentheses. 2r: GCF (d-2): Factors
2r(d-2)
Answer:

Step-by-step explanation:
For this problem i assume that the two lines that look parallel, are parallel
step 1
Find the value of x
we know that
----> by corresponding angles
solve for x
step 2
Find the value of y
we know that
---> by vertical angles
substitute the value of x


<em>Alternative method</em>
---> by vertical angles
---> by alternate exterior angles
Solve the system of equations
Answer:
x>-2
Step-by-step explanation:
-3x+2<8
Subtract 2 from each side
-3x+2-2<8 -2
-3x < 6
Divide each side by -3. remembering to flip the inequality
-3x/-3 >6/-3
x>-2
-7x ≥ 56.
Divide both sides by -7, and the inequality sign reverses, because we are dividing by a negative number.
The sign also reverses when you multiply both sides of inequality by a negative number.
-7x/-7 ≤ 56/-7
x ≤ -8
The answer is the first option.
<span>{x | x ≤ -8}
</span>
This simply means x, such that x is less than or equal to -8.
I hope this helped.
