Answer:
x = 10.25
y = 6.7
Step-by-step explanation:
X = 8 - (-2.25) = 10.25
Y = 6 - 4.2 - (-4.9) = 6.7
Answer:
B=10
Step-by-step explanation:
It's a perfect square of equation ax²+2abx+b²
I'm the given equation a is 1 and b is 5 so 2(a)(b)=2(1)(5)=10
(ps: when I say b in the explanation I mean another b not the one in question as to not be confused)
Answer:
B. 110.5 square units
Step-by-step explanation:
The area of a rhombus is half the product of the diagonals.
A = (MK * JL)/2 = 13 * 17/2 = 221/2 = 110.5
L, A, B = the amount of money each person has.
L + A + B = 70
B = 3L
L = A +5 or A = L-5
Set up an equation in L only:
L + L - 5 +3L =70
5L -5 = 70
5L =75
L = 15
follows
B=3*15 =45
A = 15 - 5 = 10
You have line XYZ, and XY + YZ = 57.
YZ = 28.
Therefore, XY + 28 = 57.
XY = 29.
