For a perfect square
b² = 4*a*c
Comparing ax² + bx + c = 0 to x² + bx + 16
a = 1, c = 16
<span>b² = 4*a*c
</span>
<span>b² = 4*1*16
</span>
<span>b² = 64
</span>
b = √64
b = 8
The value of b = 8.
Answer:
The area is 452cm
Step-by-step explanation:
For the big square we have to multiply 15*18 and that is the area so-
15*18=270
Next we multiply 13 and 14
13*14=182
And now we add 270 and 182 to get the total area
270+182=452
The square pyramid with a base with edges of 6 inches and slant height of 4 inches have a surface area of 84 in².
The net of the square pyramid have a base of 6 inches and the height of each triangle is 4 inches.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The square pyramid with a base with edges of 6 inches and slant height of 4 inches. Hence:
Surface area = (6 * 6) + 2(6 * 4) = 84 in²
The net of the square pyramid have a base of 6 inches and the height of each triangle is 4 inches.

Rosa has saved $490 in 6 weeks.
To find the answer to this, simply plug the number of weeks in for the value of x and solve.
f(x) = 250 + 40x
f(6) = 250 + 40(6)
f(6) = 250 + 240
f(6) = 490
