Yes, you are right.........
Answer:
16x + 8y -3/2
Step-by-step explanation:
The expression can be represented mathematically as follows.
-2(-8x - 4y + 3/4) = - 10x - 8y - 1 1/4
-2(-8x - 4y + 3/4) = - 10x - 8y - 5/4
The first way to solve this expression is by opening the bracket by multiplying the outside values by the inner values.
-2(-8x - 4y + 3/4)
Multiply -2 by all the values in the brackets
-2 × - 8x = 16x not - 10x
-2 × - 4y = 8y not -8y
-2 × 3/4 = -6/4 = - 3/2 not -5/4
Bringing the value together the expected answer will be 16x + 8y -3/2 and not - 10x - 8y - 5/4.
Answer:
x = 4
Step-by-step explanation:
This is an isosceles triangle since the base angles are congruent.
If we know it's an isosceles triangle then we know that the legs of it are congruent.
9x - 8 = 28
9x = 36
x = 4
X=the shortest leg
X+1= the longest leg
X+9=the hypotenuse.
Apply the Pythagorean theorem(a^2+b^2=c^2):
X^2 + (x+1)^2 = (x+9)^2
The sides=
20, 21, and 29
18.92 that is at least what i would put.
