Answer:
-4.88
Step-by-step explanation:
-5+(-3) = (-8)
7/10 = 98/140
3/7 = 60/140
15/4 = 525/140
525/140 + 60/140 + 98/140 = 683/140
683/140 = 4 123/140
4 123/140 = 4.88 (2dp)
4.88+(-8) = -4.88

72/4=18
18x5=90
Multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6
<h3>How to expand quadratic equations?</h3>
We want to expand the quadratic equation given as;
(x + 2)(4x - 3)
Multiplying out gives us;
4x² + 8x - 3x - 6
⇒ 4x² + 5x - 6
Thus, we can conclude that multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6

Answer:
A = 48 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
here b = 16 and h = 6 , then
A = × 16 × 6 = 8 × 6 = 48 ft²
Answer:
12 units
Step-by-step explanation:
From the given figure, it can be seen that AB=BC, thus
From ΔBEC, using the Pythagoras theorem, we have
Now, from ΔABE, using the Pythagoras theorem, we have
Thus, the measure of AE is 12 units.
