Answer:
22
Step-by-step explanation:
since there is a bisector that makes the two angles equal. you first need to find x then with x you can add the angles to get the biggest angle witch is RMQ
2x+1 = 4x-9
1=2x-9
10=2x
5=x
x=5
RMQ=2x+1+4x-9
RMQ=2(5)+1+4(5)-9
RMQ=10+1+20-9
RMQ=11+11
RMQ=22
RMQ=16
Answer:
42 square yards
Step-by-step explanation:
T.S.A of cube

where l = 7yd

thus, the surface area of cube is 42 square yards
Answer:
vertex =
(
4 , 25
)
Step-by-step explanation:
given a parabola in standard form y
= a
x
2
+
b
x
+
c
x
;
a
≠
0
then the x-coordinate of the vertex is
X vertex=-b/2a
y=-x2+8x+9 with a=-1 b=8 c=9
X vertex= -8/-2=4
substitute the value on the equation
Y vertex = -(4)squared+8(4)+9=25
im pretty sure the answer is 0.7
