Step-by-step explanation:
PQR=STV
angPQR=angSTV
angPRQ=angSVQ
Both triangle are similar by AA test
therefore,
PQ/ST=QR/TV
30/ST=36/24
ST=36*30/24
<h3>
ST= 45</h3>

Answer:
a parallelogram is a rectangle so the sides are 3cm and the other two are 7cm
Step-by-step explanation:
how to calculate the area is u multiply 7 by three and there is your answer
Answer:
soln
let x=n in order to differentiate btn x and multiplication sign.
first of all we apply cross multiplication.
14/4×n/2
(4×n)=(14×2)
open blacket
4n=28
we divide by 4 both side
n=7
therefore
x=7
Answer:
Option D. 9
Step-by-step explanation:
There are two ways to obtain the answer to the question.
Method 1:
Let 2x + 1 = 0
Making x the subject, we have
2x + 1 = 0
Collect like terms
2x = –1
Divide both side by 2
x = –1/2
Now, put the value of x into the expression 4x³ – 6x² – 8x + 7, we have:
4x³ – 6x² – 8x + 7
x = –1/2
4(–1/2)³ – 6(–1/2)² – 8(–1/2) + 7
4(–1/8) – 6(1/4) – 8(–1/2) + 7
–1/2 – 3/2 + 4 +7
– 4/2 + 4 + 7
– 2 + 4 + 7
= 9
Method 2:
Divide 4x³ – 6x² – 8x + 7 by 2x + 1
