Plz Help I dont Understand The question is Select all true statements in the expression: -3 + x + y + 0.5
A. The coefficient of the variable y are 1
B. 0.5 is one of the coefficients
C. -3 is one of the constants
D .-3 and 0.5 are like terms. They can be added or subtracted.
E. -3 +x +y +0.5 = xy - 2.5

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

i think c. but don't trust it.

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
