Answer:
A
Step-by-step explanation:
f(x)+g(x)=-3x^2+4x+4+x(-7x-7)= -3x^2+4x+4 -7^2-7x
= -10x^2-3x+4
Answer:
(2x^2+7)
Step-by-step explanation:
5x^3 * 2x^2 = 10x^5
5x^3 * 7 = 35x^3
Answer:
x = 6
NO = 26
Step-by-step explanation:
recall that for a rhombus all the sides are of equal length,
which means, PM = MN = MP = NO
we are given
MP = 5x-4 and MN = 6x-10
since MP = MN, thus
5x-4 = 6x-10 (add 4 to both sides)
5x = 6x - 10 + 4
5x = 6x - 6 (subtract 6x from both sides)
5x-6x = -6
-x = -6
x = 6 (answer)
NO = MP = 5x-4 = 5(6) - 4 = 30 - 4 = 26
Answer:
Kristen would be 7.5 yo and Nicole would be 24.5 years old
Step-by-step explanation:
let x= kristen's age
3x+2= nicole's age
(3x+2)+x=32
4x+2=32
4x=30
x=7.5
3(7.5)+2= 24.5
Answer:
782 yd²
Step-by-step explanation:
Since the diagonals are perpendicular bisectors of each other, then
area = 0.5 × product of diagonals
area = 0.5 × 34 × 46 = 782 yd²
