Answer:
B
Step-by-step explanation:
-4x+2x>-4 is simplified to x>0. B graph correctly shows this.
Answer:
Step-by-step explanation:
for 2.2 you would still have 5^2 in brackets still
same kind of error for 2.1
X^2 - x - 42 = x^2 - 6x + 7x - 42 = x( x - 6) + 7(x - 6) = (x-6)(x+7);
The correct answer is a.
0 because the -x cancels out the ones negative and 1 x 2 is 2. And 2-2 is 0
Answer:
The correct answer is option B. 8,16, 20
Step-by-step explanation:
Its given that,ΔJKL ~ ΔPQR, with a scale factor of 3 : 4
The sides of ΔJKL are, 6,12,15
Let 'x', 'y', and 'z' be the sides of ΔPQR
We know that if two triangles are similar, then the ratio of corresponding sides are in same raio.
<u>To find x</u>
6/x = 3/4
x = 8
<u>To find y</u>
12/y = 3/4
y = 16
<u>To find z</u>
15/z = 3/4
z = 20
Therefore the sides of ΔPQR are 8,16 and 20
Option B. 8,16,20 is the correct answer
