Answer:

x = (+ - ) 9

Step-by-step explanation:

x^2 = 81

u know how u can sometimes cancel something out by doing the opposite.

This is one of those times as well. the opposite of ^2 = square root.

so if we take the square root of both sides, this will cancel out the^2 on the left side.

sqrt (x^2) = sqrt(81)

x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.

In parallelogram ABCD, m∠BAC = 40.62°and m∠BCA = 30.96°. What is m∠BAD?
KatRina [158]
The answer is letter a.  m∠BAD = 108.42<span>° 

The solution is as follows:
If </span>m∠BAC = 40.62° and m∠BCA = 30.96°, then
m∠CBA = 180° -  m∠BCA - <span>m∠BAC
</span>m∠CBA = <span>108.42°
</span>
Since m∠BAD = m∠CBA  due to the parallelogram's property, 
<span>m∠BAD</span> = <span>108.42°.</span>

Answer:

\boxed{\bold{True}}

\boxed{\bold{True}}

Step By Step Explanation:

Equation One:

Multiply Both Sides By One (Reverse The Inequality)

\bold{\left(-\frac{2}{5}x\right)\left(-1\right)

Simplify

\bold{\frac{2}{5}x

Multiply Both Sides By 5

\bold{5\cdot \frac{2}{5}x

Simplify

\bold{2x

Divide Both Sides By 2

\bold{\frac{2x}{2}

Simplify

\bold{x

-------

Equation Two:

Subtract \bold{\frac{3}{4} } From Both Sides

\bold{-x+\frac{3}{4}-\frac{3}{4}

Simplify

\bold{-x

Multiply Both Sides By -1 (Reverse The Inequality)

\bold{\left(-x\right)\left(-1\right)>\frac{37\left(-1\right)}{4}}

Simplify

\bold{x>-\frac{37}{4}}

<h2>Answer:</h2>

[1] Area of base = 13 × 13 = 169in².

Area of faces = 4 (1/2 × 13 × 8) = 208in².

Surface area = (169 + 208)in² = 377in².

[2] Area of base = 1/2 × 5.2 × 4.5 = 11.7in².

Area of faces = 3 (√3/4 × 5.2²) = 35.1in².

Surface area = (35.1 + 11.7)in² = 46.8in².

[3] Area of base = 7 × 10 = 70in².

Area of faces = 2(1/2 × 7 × 6) + 2(1/2 × 10 × 4.8)

= 98in².

Surface area = (70 + 98)in² = 168in².
