In order to find b1 from your formula stated we need to do few calculations
A=hb1+hb2, as you wee I multiply h with both bases( b1 and b2)
I will subtract hb2 from both sides
hb1=A-hb2
now I will divide my new expression by h
b1=(A-hb2)/h

Answer:
Angle = 45
Step-by-step explanation:
It is half of a right angle also (x = 15) :)
Hello :
<span>y = 3x2 + 24x - 1
= 3(x²+8x) -1
= 3 (x² +2(4)(x) +4²- 4² ) -1
= 3((x+4)² -16)-1
y = 3(x+4)² - 49
</span><span>the line of symmetry is : x= - 4</span>
Answer:100-7x
Step-by-step explanation:
If x people are coming, he will spend the following
Sandwiches =2.50 × x= 2.50x
Drinks = 1.50 × x= 1.50x
Gift bags =3 × x=3x
Money left
Sandwiches = 50-2.50x
Drinks =25-1.60x
Gift bags = 25-3x
Total money left = 50-2.50x+25-1.50x+25-3x
=50+25+25-2.50x-1.50x-3x
=100-7x
